Description
The forms of TN as part of syndromes include argininosuccinic aciduria, citrullinemia, and trichohepatoenteric syndrome [ 43 ]. TN can occurs in association with monilethrix, trichothiodystrophy, Netherton syndrome, and Menkes syndrome as a response to injury of otherwise damaged hair shaft [ 41 ]. Argininosuccinic aciduria and citrullinemia are a group of urea cycle disorders caused by a deficiency of enzymes required to convert toxic ammonia into urea. Clinical manifestations of these diseases are mostly due to hyperammonemia, which affects the central nervous system.
Affected individuals may also develop hepatic dysfunction [ 44 ]. Argininosuccinic aciduria is an inborn error of urea synthesis. It is due to deficiency of argininosuccinic lyase. If untreated, it may present with failure to thrive and mental retardation. The hair finding of TN is an important diagnostic clue in this syndrome. These patients have normal hair at birth but then develop TN when they are 1—2 years of age [ 45 ]. Citrullinemia is also a rare genetic error of the urea cycle. There is a deficiency of argininosuccinate synthetase, resulting in increased blood ammonia, citrullinemia, and decreased arginine level [ 46 ]. Patients with this syndrome have abnormally fragile visit web page with TN [ 46 ].
Treatment of TN is challenging in its genetic form are thin lips genetic disorder it is dependent mainly on managing the underlying disorder. They had associated alopecia and dry scaly skin. The treatment enhanced the hair growth, despite persistence of TN microscopically. One of them had are thin lips genetic disorder zinc level at initiation of the therapy [ 47 ]. In trichorrhexis invaginata TIalso known as Bamboo hair, the hair shaft invaginates at several click along its length Fig. Low magnification trichoscopy shows multiple small nodules spaced at irregular intervals.
With high magnification trichoscopy, it is possible to see invagination of the distal part of the shaft into what ingredients make lip gloss so shiny easy proximal part, forming a ball in a cup appearance. Sometimes the proximal cupped end may be seen after the distal end has fractured golf tee sign [ 48 ] Fig. Trichorrhexis invaginate under microscopy. Invagination of the distal part of the hair shaft into its proximal part forming a ball in a cup appearance. Trichoscopic finding in trichorrhexis invaginate. Note the invagination of the distal part of the shaft into its proximal part forming a ball in a cup appearance are thin lips genetic disorder arrow. Proximal cupped end also seen after the distal end has fractured golf tee sign red arrow.
Netherton syndrome is characterized by a triad of congenital ichthyosiform erythroderma CIE or ichthyosis linearis circumflexa ILCatopic diathesis elevated serum IgEand short sparse fragile hair with trichorrhexis invaginata [ 49 ]. Hair improves with aging, but the eyebrows usually exhibit some hairs with the abnormality and should be checked for diagnosis [ 50 ]. Other hair findings in patients with See more syndrome may resemble pili torti-like, trichorrhexis nodosa-like, and helical hairs [ 51 ].
Monilethrix beaded hair comes from monile necklace, in Latin and thrix hair, in Greek. It is most dislrder transmitted as an autosomal dominant disease [ 55 ], with high penetrance and variable genteic [ 56 ]. An autosomal recessive form has been described, caused by a mutation in the DSG4 gene, encoding for desmoglein 4 protein [ 58 ]. The scalp hair is usually normal at birth. Within a few weeks to months, the consider, who initiated the first step acting process definition opinion is then replaced by dull, dry, and brittle hair which break easily, leaving a stubble-like appearance.
The hair on the nape of the neck and occipital area are thhin most commonly affected areas and is usually accompanied by follicular keratosis [ 59 ] Fig. Lanugo genetid is normal in the neonatal period, and clinical signs of monilethrix appear when the terminal hair begins to form [ 60 ]. In most cases, hair growth will be a maximum of 8 cm in length, but mild cases with hair of almost normal length can occur [ 41 ]. Eyebrows, eyelashes, and body hair can be affected, too [ 61 ]. The condition can be associated with keratosis pilaris, koilonychia, retarded growth, and juvenile cataract [ 62 ]. Clinical picture of monilethrix. Alopecia is more severe in the occipital region that also presents keratotic follicular papules. Trichoscopy will show normal medullated nodes of hair, along with non-medullated internodal thin hair at regular intervals Fig. The internode represents the diseased abnormal hair where it can be are thin lips genetic disorder fractured [ 63 ]. Light microscopy shows typical beaded or moniliform appearance of the hair.
Trichoscopic finding in monilethrix. Typical beaded or moniliform appearance of the lipz. Monilethrix usually persists into adulthood but may genetiv at puberty, pregnancy, or with an grnetic contraceptive [ 64 ]. Variable results have been obtained from systemic retinoid therapy where etretinate at 0. Low dose of oral minoxidil was tried on two women with good treatment response after 6 months [ 68 ]. Gentle hair care may diminish ade and improve the condition [ 68 ]. Pili torti PT is a hair shaft disorder characterized by a flattened hair shaft that irregularly twists over its own axis. This finding can be seen via light microscopy and trichoscopy [ 69 ] Fig. Although a few pili torti hairs are commonly seen in association with other hair shaft disorders, there are rare conditions where pili torti is the exclusive https://agshowsnsw.org.au/blog/what-song-is-this/how-to-check-kisan-card-apply-status-rajasthan.php [ 41 ].
In classic early onset pili torti, it can be associated with other, usually minor, ectodermal abnormalities. Both autosomal dominant and recessive forms have been reported. Females are most commonly affected, where they are born with abnormal hair or normal hair that is replaced with fragile, spangled, easily broken hair at are thin lips genetic disorder levels. Eyebrows aree eyelashes can be affected. This condition improves with puberty [ 70 ]. Trichoscopic feature of pili torti. Note the flattened hair shaft that twists over its own axis. Late onset Beare pili torti is an autosomal dominant condition in are thin lips genetic disorder the eyebrows and eyelashes are broken off with an early age of onset, then the scalp hair after puberty becomes coarse, stiff, and jet black [ 71 ]. Bjornstad syndrome: Autosomal recessive condition. The patient will have both pili torti and sensorineural hearing loss.
It is caused by mutations in the BCS1L gene [ 72 ]. Crandall syndrome: Autosomal recessive condition. The patient will have pituitary hormones dysfunction, hypogonadism, pili torti, and deafness [ 73 ]. Menkes syndrome: X-linked recessive condition. The patient will have sparse, pale, lightly pigmented hair with a steel wool appearance. Eyebrows are affected, too. The skin is pale and doughy with a bowed upper lip. There will be associated vascular, neurological, and skeletal dysfunction due to decrease in activity of copper-dependent enzymes [ 74 ]. It is characterized by triad of 1 follicular atrophoderma, especially on the dorsum of hands and feet, 2 multiple basal cell carcinomas on the face, occurring mainly during the second decade of life, and 3 congenital generalized hypotrichosis with associated hair shaft are thin lips genetic disorder pili torti, trichorrhexis nodosa [ 75 ].
The expression of these main features may vary [ 76 ]. Common associated symptoms are milia and hypohidrosis [ 77 ].
Trichothiodystrophy TTD is an autosomal recessive condition characterized by low sulfur or cysteine levels on the hair. Varying degrees of clinical presentations from isolated hair shaft are thin lips genetic disorder to a more severe developmental delay, intellectual disability, recurrent infections, and even death at early childhood [ 78 ]. The PIBIDS acronym refer to photosensitivity, ichthyosis, brittle hair, intellectual impairment, decrease fertility, and short stature [ 79 ]. About half of the cases with TTD have photosensitivity. Light microscopy will show trichoschisis transverse fracture through the hair shaft with or without trichorrhexisis nodosa [ 80 ].
Both trichoschisis and alternating light and dark bands tiger tail are visible under polarized light [ 81 ]. Pili annulati PA is sporadic or autosomal dominant, and clinically presents as speckled-appearing or shiny spangled scalp hair. The PA locus has been mapped to chromosome 12q The hair shaft presents alternating light and dark bands. Trichoscopy features include bright bands caused are thin lips genetic disorder light scattered from clusters of air-filled cavities in are thin lips genetic disorder hair [ 84 ] Fig. These air-filled cavities appear dark on light microscopy [ 85 ]. Usually PA is not associated with hair fragility; however, a few cases associated with severe hair fragility have been reported [ 8687 ]. Furthermore, two patients were described in the literature with pili annulati in whom fragility of hair developed in a causal relationship with the onset of androgenetic alopecia [ 88 ].
There are a few diseases that have been reported to be associated with PA including autoimmune thyroid disease and primary immunoglobulin A deficiency [ 85 ]. PA carries excellent prognosis and treatment is usually unnecessary [ 89 ]. Cases of PA article source association read more alopecia areata have been reported even though the association is possibly coincidental. Woolly hair WH is a group of hair shaft disorders characterized by short, kinked, tightly curled hair [ 91 ] Fig. Trichoscopic examination reveals that the hair shafts have waves at short intervals [ 69 ]. HWH is an autosomal dominant form with a variable degree of read article curling.
It presents in hairs all over the scalp. Usually the hair density is normal in HWH and hair color is variable.

A missense mutation within the helix initiation motif of the keratin K71 gene causes the dominant form [ 91 ]. Moreover, the dominant form has been described with disruption of keratin 74 [ 93 ]. WHN is considered the isolated or localized type of WH and characterized by a well-demarcated area that is lighter than the normal hair and has a smaller diameter [ 92 ]. When WH is accompanied by palmoplantar keratoderma, it may be associated with fatal cardiomyopathy like Carvajal syndrome or Naxos syndrome [ 96 ], and hence this condition should alert the physician to a cardiac disease [ click here — 99 ].
Carvajal syndrome is an autosomal recessive disorder due to a desmoplakin gene mutation. It is are thin lips genetic disorder by wooly hair at birth, striate palmoplantar keratoderma which develops after infancy, and left-sided ventricular cardiomyopathy. Other features include follicular keratoses on face, elbows, abdomen, and lower limbs, in addition to finger clubbing, psoriasiform keratosis, and transient pruritic blisters. The main cause of death is heart failure which can occur in adolescence. Early cardiac intervention can decrease mortality and improve prognosis [ ]. Naxos syndrome is an autosomal recessive disorder due to a plakoglobin gene mutation.
The clinical features include wooly hair at birth, diffuse palmoplantar keratosis developing during the first year of life, and arrhythmogenic right ventricular cardiomyopathy. The last of these presents by adolescence with arrhythmia and automatic implantable cardioverter defibrillator is usually are thin lips genetic disorder which may prevent sudden death [ ]. WH may be an isolated finding make pink lips balm with honey associated with additional clinical symptoms. WH has been reported with keratosis pilaris [ 69 ], congenital ichthyosis [ 99 ], Noonan syndrome, cardiofaciocutaneous syndrome [ ], osteoma cutis [ ], nail dystrophy [ ], and severe neurologic disorders [ ].
Click here is most evident during childhood; the appearances can become less severe in adulthood since the manageability improves with age [ ]. However, some individuals do not improve with age [ ]. Treatment with nonablative fractional lasers stimulated normal hair growth in three adult men with autosomal recessive WH [ ]. Pili trianguli et canaliculi most often presents in infancy or early childhood, with spun-glass-appearing scalp hairs that are dry, curly, blond, and totally resist all efforts of styling [ ]. Hair is not fragile and grows normally [ ]. Most reported source are sporadic, but autosomal dominant and autosomal recessive inheritance has been described [ ].
Electron microscopy reveals irregularly shaped triangular shafts on cross section, which are areas of the internal root sheath that have been abnormally keratinized. In most cases of uncombable hair syndrome, the hair texture and manageability improve with ageing [ ]. Ectodermal dysplasias include a big group of disorders characterized by isolated or associated abnormalities in the teeth, hair, nails, and sweating function [ ]. These disorders may also include abnormalities in other ectoderm-derived structures such as the meibomian glands, mammary glands, branchial arch cartilages, and pigment cells, anterior pituitary, thymus, and melanocytes [].

Hair is the most frequent are thin lips genetic disorder affected by ectodermal dysplasias [ ], with manifestations of alopecia and hypotrichosis. Common trichoscopic findings in ectodermal dysplasia include follicular units with a single hair, abnormalities in hair shaft pigmentation, pili torti, trichoschisis, pili canaliculi, trichorrhexis are thin lips genetic disorder, and pseudomonilethrix [ ]. Hypohidrotic ectodermal dysplasia HED is an ectodermal dysplasia which principally causes sparse hair, the inability to sweat, and abnormal or missing teeth Fig. The X-linked form is the most common, occurring in approximately 1 in 17, live births [ ]. Males are disproportionately affected by the X-linked HED; however, approximately one-third of cases are inherited in either an autosomal recessive or autosomal dominant pattern, of which males and females are affected equally [ ].
These mutations disrupt communication between surface epithelial cells and the underlying mesenchyme during embryonic development, thereby impairing the development of skin appendages [ ]. Hypohidrotic https://agshowsnsw.org.au/blog/what-song-is-this/easy-clear-lip-gloss-recipe-ingredients.php dysplasia. Scalp hair is thin, sparse, slow-growing, and lightly pigmented. Note the flat nasal bridge. Hypohidrosis due to hypoplasia of sweat glands leads to fevers as a child and heat intolerance throughout life, especially during exercise [ ]. Hypodontia is seen with an average of nine permanent more info in patients with HED, which are frequently smaller than normal and with altered shape [ ].
Patients with HED exhibit a typical facies with prominent forehead, thick lips, and a flattened nasal bridge [ ]. Scalp hair is thin, sparse, slow-growing, and lightly pigmented, though secondary sexual hair can be normal [ ]. In microscopic hair analysis of 22 patients with HED, investigators found an increased incidence of variable shaft thickness, trichorrhexis nodosa, and pili torti compared to normal controls [ ]. Phototrichogram analysis in a control-matched group of 12 patients with HED showed significantly decreased number of terminal hairs, decreased number of follicular units, decreased number of hairs per follicular unit, decreased terminal hair width, and decreased hair growth rate [ ].
No specific guidelines for diagnosing HED have been published. Individuals are typically diagnosed during infancy as a result of the characteristic features of hypotrichosis, hypohidrosis, and hypodontia and typical facies [ ]. Hypohidrosis can be confirmed with the starch—iodine test. Biopsy is not routinely performed; however, horizontally sectioned 4-mm punch biopsy specimens of the scalp or palms that lack eccrine structures are diagnostic of HED; scalp biopsy is much more sensitive than palmar biopsy [ ]. There is currently no cure for HED, so treatment is focused on managing symptoms. It is important for HED are thin lips genetic disorder to control their exposure to heat in light of their hypohidrosis. During hot weather, they should have access to a cool environment and plenty of water. EDI is a targeted therapy that has been shown to be effective in preventing manifestation of the disease when administered to newborn X-linked HED dog and mouse animal models [ ].
These benefits persisted through adulthood in these animals. However, a phase II clinical trial ClinicalTrials. The disease is most frequently associated with those of French—Canadian descent [ ], but has been seen in other ethnicities. Unlike hypohidrotic ectodermal dysplasia, patients with Clouston syndrome have the ability to sweat and have normal dentition. Patients with Clouston exhibit pale-colored, patchy, wiry, and brittle scalp hair during infancy, with progressive hair loss typically leading to total alopecia by puberty. Eyebrows, axillary, and pubic hair are sparse or absent, and eyelashes are short and sparse [ ]. Hair abnormalities under light microscopy include trichorrhexis nodosa, trichoptilosis, pili bifurcati, variable diameter, damaged cuticles, and irregular helical twists [].
Electron microscopy of the abnormal hair shows a square shape in transverse section and longitudinal grooving [ ]. Clouston syndrome should be suspected in individuals with nail dystrophy, hypotrichosis, and palmoplantar hyperkeratosis starting early in life [ ]. The diagnosis can be confirmed by genetic analysis. The best initial genetic test is targeted analysis for the four known GJB6 pathogenic variants, and if initial testing is inconclusive, sequence analysis can be are thin lips genetic disorder [ ]. There is no cure for Clouston disease; its treatment involves management of symptoms. Artificial nails may be used to improve appearance of nails.
Skin emollients may improve palmoplantar hyperkeratosis [ ]. Rapp—Hodgkin syndrome is distinguished from AEC syndrome by the absence of ankyloblepharon [ ]. Once thought to be separate disorders, the two diseases are now considered to be varying presentations of the same genetic disease [ — ]. AEC syndrome is due to a mutation in the TP63 gene, coding https://agshowsnsw.org.au/blog/what-song-is-this/how-to-watch-kissing-booth-2-now-live.php the p63 protein, which is involved in epidermal differentiation [ ]. Additional symptoms include dental hypoplasia, nail dysplasia, decreased sweating, and hair symptoms described below [ ]. Scalp hair loss frequently begins at puberty and continues through the 20s and 30s, and typically affects the frontal hairline to the crown, with relative sparing of the occipital and temporal regions, but often leads to almost complete hair loss [ ].
Absence or thinning of eyebrows and eyelashes is common, and body hair is usually sparse. Varying severity of Rapp—Hodgkin syndrome can manifest with different degrees of hair symptoms. Clinical picture of AEC syndrome with scalp erosions leading to scarring alopecia and hypotrichosis. Diagnosis can be suspected owing to the characteristic clinical features described above, and can be confirmed with sequence analysis of the TP63 gene [ ]. Treatment focuses on management of symptoms. Neonatal scalp skin erosions should be treatment with dilute bleach soaks in order to prevent secondary infection [ ], perhaps decreasing incidence of scarring alopecia after healing. Cleft lip and palate can be corrected by surgery, and ankyloblepharon typically resolves on its own but may be corrected by an ophthalmologist if necessary [ ].
The use of topical minoxidil has been proposed and its effectiveness in certain types of epidermal dysplasia is supported by isolated case reports, used either on its own [ ] or in combination with topical tretinoin [ ]. Using only topical minoxidil is probably the safer option due to possibility of side effects when used in combination with tretinoin, such as eruptive pyogenic granuloma [ ]. Some surgical techniques have been used with success. Patients are generally poor candidates for hair transplant because of lack of sufficient donor sites [ ]. However, autologous hair transplantation has been used to replace eyebrows in a patient with ectodermal dysplasia [ ]. Tissue expansion surgery has been successfully used to correct areas of alopecia in a patient with hypohidrotic ectodermal dysplasia [ ].
Patients may opt for use of a wig. Clinical features include a large pear-shaped nose, thick and broad eyebrows, prominent ears, short stature, short digits, cone-shaped epiphyses, dystrophic nails, and fine, sparse hair. The hair of patients with TRPS is typically fine, sparse, slow-growing, and not very pigmented [ ]. The pathologic change and pattern of hair loss is similar to that seen in male pattern baldness, with recession of the frontotemporal hairline link thinning of hair diameter [ ]. Approximately one-third of males go nearly or completely bald within a few years after puberty, while women typically keep most of their hair but have a high frontal hairline [ ]. Read more may have sparse lateral eyebrows and eyelashes [ ].
Scanning electron microscopy of the hair shaft may be normal or show changes in cuticular pattern and hair shaft structure [ ]. Light microscopy may show thinning of the distal end of the hair shaft, trichorrhexis nodosa, and trichoptilosis [are thin lips genetic disorder. In mice, the TRPS1 gene has been shown to be involved in the Wnt signaling pathway, involved in follicle morphogenesis. TRPS1 protein expression has been shown to be regulated by androgens [ ], providing a possible mechanism for why hair loss seen in TRPS can mimic male pattern baldness. Diagnosis can typically be made clinically on the basis of typical findings.
Despite similarities in appearance to male pattern baldness, topical minoxidil and oral finasteride have not been shown to be effective in patients are thin lips genetic disorder TRPS. Hair transplant has been shown to be a viable option in these patients, with favorable results seen at 3-year follow-up [ ].

In patients for whom hair transplant is not an option, the use of wigs can be considered if desired [ ]. Atrichia with papular lesions APL is a rare autosomal recessive disease with irreversible alopecia of the scalp, eyebrows, axillary, and pubic hair, which starts a few months after birth and is associated with development keratin cysts over the body [ ]. It is due to mutation in the zinc finger domain of human hairless gene HL on chromosome region 8p12 [ ]. The hair matrix cells in APL undergo premature apoptosis associated with loss of neural cell adhesion molecule positivity and disconnection from overlying epithelial sheath. Lanugo hairs are present at birth, but the alopecia is complete within the first year of life as the catagen follicles are unable to re-enter the anagen phase. Progressive keratin retention into follicular structures results in cyst formation, clinically evident as papules [ ].
Histology of this disorder shows the infundibular part of the hair follicle with replacement of the middle and lower part by keratinizing cysts. Differential diagnosis includes vitamin D-resistant rickets type II, which also causes total alopecia in early life. It is due to a mutation of vitamin D receptor VDRsuggesting that VDR and HL gene, both of which are zinc finger proteins, may be involved in the same genetic pathway of hair follicle control [ ]. Another clinical differential diagnosis of APL is alopecia universalis AUso AU should be excluded to avoid the need for systemic steroid and immunosuppressive medication [ ]. Diagnostic criteria of this disorder were revised by Yip et al. Permanent and complete absence of scalp hairs by the first few months of life.

Do you have more information about symptoms of this disease? We want to hear from you. Do you have updated information on this disease? Cause Cause. Rarely, it may be caused by a mutation in the COL1A1 gene. Collagen is a protein that provides structure and strength to connective tissues throughout the body.
Type III collagen, specifically, is found in tissues click as the skin, lungs, intestinal walls, and the walls of blood vessels. This causes the many signs and ae associated with vascular EDS. Type I collagen is the most abundant form of collagen in the human body. Inheritance Inheritance. Vascular Ehlers-Danlos syndrome is typically inherited in an autosomal dominant manner. In some cases, an affected person inherits the mutation from an affected parent. Other thln may result from new de novo mutations in the gene.
These cases occur in people with no history of the disorder in their family. Diagnosis Diagnosis. A diagnosis diskrder vascular Ehlers-Danlos syndrome is typically thi on the presence of characteristic signs and symptoms. Collagen is a tough, fiber-like protein that makes up about a third of body protein. It is part of the structure of tendons, bones, and connective tissues. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. Treatment Treatment. The treatment and management of vascular Ehlers-Danlos syndrome EDS aims to relieve signs and symptoms and prevent serious complications. For example, people with vascular EDS have tissue fragility that puts them at high risk for rupturing of arteries, muscles and internal organs. It is therefore important to seek immediate medical attention for any sudden, are thin lips genetic disorder pain because emergency surgery may be needed.
Pregnant women with vascular EDS should be followed by a maternal-fetal medicine specialist at a center for high-risk pregnancies. The risk of injury should be minimized click the following article avoiding contact sports, heavy lifting, and weight training. Elective surgery is also discouraged.

Prognosis Prognosis. The long-term outlook prognosis for people with gsnetic Ehlers-Danlos syndrome is generally poor.
It is typically considered the most severe form of EDS and is often associated with a shortened lifespan. The median life expectancy for people affected by vascular EDS is 48 years. Find a Specialist Find a Specialist. To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. You can also learn more about genetic consultations from MedlinePlus Genetics.
