Conditions with this feature

Hallermann-Streiff syndrome
MedGen UID:
5414
Concept ID:
C0018522
Disease or Syndrome
Hallermann-Streiff syndrome is characterized by a typical skull shape (brachycephaly with frontal bossing), hypotrichosis, microphthalmia, cataracts, beaked nose, micrognathia, skin atrophy, dental anomalies, and proportionate short stature (Hallermann, 1948; Streiff, 1950; Francois, 1958). Mental retardation is present in a minority of cases (Gorlin et al., 1990).
Hypohidrotic X-linked ectodermal dysplasia
MedGen UID:
57890
Concept ID:
C0162359
Disease or Syndrome
Hypohidrotic ectodermal dysplasia (HED) is characterized by hypotrichosis (sparseness of scalp and body hair), hypohidrosis (reduced ability to sweat), and hypodontia (congenital absence of teeth). The cardinal features of classic HED become obvious during childhood. The scalp hair is thin, lightly pigmented, and slow growing. Sweating, although present, is greatly deficient, leading to episodes of hyperthermia until the affected individual or family acquires experience with environmental modifications to control temperature. Only a few abnormally formed teeth erupt, at a later-than-average age. Physical growth and psychomotor development are otherwise within normal limits. Mild HED is characterized by mild manifestations of any or all the characteristic features.
Hidrotic ectodermal dysplasia syndrome
MedGen UID:
56416
Concept ID:
C0162361
Disease or Syndrome
Hidrotic ectodermal dysplasia 2, or Clouston syndrome (referred to as HED2 throughout this GeneReview) is characterized by a triad of major clinical features including partial-to-complete alopecia, nail dystrophy, and palmoplantar hyperkeratosis. Sweating is preserved and there are usually no dental anomalies. Sparse scalp hair and dysplastic nails are seen early in life. In infancy, scalp hair is fine, sparse, and brittle. Progressive hair loss may lead to total alopecia by puberty. The nails may be milky white in early childhood; they gradually become dystrophic, thick, and distally separated from the nail bed. Palmoplantar keratoderma may develop during childhood and increases in severity with age. Associated features may include cutaneous hyperpigmentation (particularly over the joints) and finger clubbing. The clinical manifestations are highly variable even within the same family.
Metaphyseal chondrodysplasia, McKusick type
MedGen UID:
67398
Concept ID:
C0220748
Congenital Abnormality
The cartilage-hair hypoplasia – anauxetic dysplasia (CHH-AD) spectrum disorders are a continuum that includes the following phenotypes: Metaphyseal dysplasia without hypotrichosis (MDWH). Cartilage-hair hypoplasia (CHH). Anauxetic dysplasia (AD). CHH-AD spectrum disorders are characterized by severe disproportionate (short-limb) short stature that is usually recognized in the newborn, and occasionally prenatally because of the short extremities. Other findings include joint hypermobility, fine silky hair, immunodeficiency, anemia, increased risk for malignancy, gastrointestinal dysfunction, and impaired spermatogenesis. The most severe phenotype, AD, has the most pronounced skeletal phenotype, may be associated with atlantoaxial subluxation in the newborn, and may include cognitive deficiency. The clinical manifestations of the CHH-AD spectrum disorders are variable, even within the same family.
Autosomal dominant keratitis-ichthyosis-hearing loss syndrome
MedGen UID:
120536
Concept ID:
C0265336
Disease or Syndrome
Keratitis-ichthyosis-deafness (KID) syndrome is a rare ectodermal dysplasia characterized by sensorineural hearing loss, photophobia and corneal vascularization, hyperkeratosis of the palms and soles, erythrokeratoderma, follicular hyperkeratosis, and recurrent bacterial and fungal infections. A subset of patients with KID may develop multiple cystic pilar tumors, which are prone to malignant transformation and metastasis (Nyquist et al., 2007). Vohwinkel syndrome (124500) is an allelic disorder involving congenital deafness with keratopachydermia and constrictions of fingers and toes. Another similar disorder caused by mutation in GJB2 is palmoplantar keratoderma with deafness (148350). Genetic Heterogeneity of Keratitis-Ichthyosis-Deafness Syndrome An autosomal recessive form of KID syndrome (KIDAR; 242150) is caused by mutation in the AP1B1 gene (600157) on chromosome 22q12.
Pallister-Killian syndrome
MedGen UID:
120540
Concept ID:
C0265449
Disease or Syndrome
Pallister-Killian syndrome (PKS) is a dysmorphic condition involving most organ systems, but is also characterized by a tissue-limited mosaicism; most fibroblasts have 47 chromosomes with an extra small metacentric chromosome, whereas the karyotype of lymphocytes is normal. The extra metacentric chromosome is an isochromosome for part of the short arm of chromosome 12: i(12)(p10) (Peltomaki et al., 1987; Warburton et al., 1987).

Concept ID:
C0406723
Disease or Syndrome
GAPO syndrome is the acronymic designation for a complex of growth retardation, alopecia, pseudoanodontia (failure of tooth eruption), and progressive optic atrophy (Tipton and Gorlin, 1984). Ilker et al. (1999) and Bayram et al. (2014) noted that optic atrophy is not a consistent feature of the disorder.
Dyskeratosis congenita, X-linked
MedGen UID:
216941
Concept ID:
C1148551
Disease or Syndrome
Dyskeratosis congenita and related telomere biology disorders (DC/TBD) are caused by impaired telomere maintenance resulting in short or very short telomeres. The phenotypic spectrum of telomere biology disorders is broad and includes individuals with classic dyskeratosis congenita (DC) as well as those with very short telomeres and an isolated physical finding. Classic DC is characterized by a triad of dysplastic nails, lacy reticular pigmentation of the upper chest and/or neck, and oral leukoplakia, although this may not be present in all individuals. People with DC/TBD are at increased risk for progressive bone marrow failure (BMF), myelodysplastic syndrome or acute myelogenous leukemia, solid tumors (usually squamous cell carcinoma of the head/neck or anogenital cancer), and pulmonary fibrosis. Other findings can include eye abnormalities (epiphora, blepharitis, sparse eyelashes, ectropion, entropion, trichiasis), taurodontism, liver disease, gastrointestinal telangiectasias, and avascular necrosis of the hips or shoulders. Although most persons with DC/TBD have normal psychomotor development and normal neurologic function, significant developmental delay is present in both forms; additional findings include cerebellar hypoplasia (Hoyeraal Hreidarsson syndrome) and bilateral exudative retinopathy and intracranial calcifications (Revesz syndrome and Coats plus syndrome). Onset and progression of manifestations of DC/TBD vary: at the mild end of the spectrum are those who have only minimal physical findings with normal bone marrow function, and at the severe end are those who have the diagnostic triad and early-onset BMF.
Trichothiodystrophy 4, nonphotosensitive
MedGen UID:

DK1-congenital disorder of glycosylation
MedGen UID:
332072
Concept ID:
C1835849
Disease or Syndrome
DOLK-congenital disorder of glycosylation (DOLK-CDG, formerly known as congenital disorder of glycosylation type Im) is an inherited condition that often affects the heart but can also involve other body systems. The pattern and severity of this disorder's signs and symptoms vary among affected individuals.\n\nIndividuals with DOLK-CDG typically develop signs and symptoms of the condition during infancy or early childhood. Nearly all individuals with DOLK-CDG develop a weakened and enlarged heart (dilated cardiomyopathy). Other frequent signs and symptoms include recurrent seizures; developmental delay; poor muscle tone (hypotonia); and dry, scaly skin (ichthyosis). Less commonly, affected individuals can have distinctive facial features, kidney disease, hormonal abnormalities, or eye problems.\n\nIndividuals with DOLK-CDG typically do not survive into adulthood, often because of complications related to dilated cardiomyopathy, and some do not survive past infancy.
Autosomal recessive congenital ichthyosis 11
MedGen UID:
332073
Concept ID:
C1835851
Disease or Syndrome
Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of disorders of keratinization characterized primarily by abnormal skin scaling over the whole body. These disorders are limited to skin, with approximately two-thirds of patients presenting severe symptoms. The main skin phenotypes are lamellar ichthyosis (LI) and nonbullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur (summary by Fischer, 2009). Neither histopathologic findings nor ultrastructural features clearly distinguish between NCIE and LI. In addition, mutations in several genes have been shown to cause both lamellar and nonbullous ichthyosiform erythrodermal phenotypes (Akiyama et al., 2003). At the First Ichthyosis Consensus Conference in Soreze in 2009, the term 'autosomal recessive congenital ichthyosis' (ARCI) was designated to encompass LI, NCIE, and harlequin ichthyosis (ARCI4B; 242500) (Oji et al., 2010). NCIE is characterized by prominent erythroderma and fine white, superficial, semiadherent scales. Most patients present with collodion membrane at birth and have palmoplantar keratoderma, often with painful fissures, digital contractures, and loss of pulp volume. In half of the cases, a nail dystrophy including ridging, subungual hyperkeratosis, or hypoplasia has been described. Ectropion, eclabium, scalp involvement, and loss of eyebrows and lashes seem to be more frequent in NCIE than in lamellar ichthyosis (summary by Fischer et al., 2000). In LI, the scales are large, adherent, dark, and pigmented with no skin erythema. Overlapping phenotypes may depend on the age of the patient and the region of the body. The terminal differentiation of the epidermis is perturbed in both forms, leading to reduced barrier function and defects of lipid composition in the stratum corneum (summary by Lefevre et al., 2006). In later life, the skin in ARCI may have scales that cover the entire body surface, including the flexural folds, and the scales are highly variable in size and color. Erythema may be very mild and almost invisible. Some affected persons exhibit scarring alopecia, and many have secondary anhidrosis (summary by Eckl et al., 2005). For a general phenotypic description and discussion of genetic heterogeneity of autosomal recessive congenital ichthyosis, see ARCI1 (242300).
Hypotrichosis 7
MedGen UID:
322969
Concept ID:
C1836672
Disease or Syndrome
Autosomal recessive hypotrichosis is a condition that affects hair growth. People with this condition have sparse hair (hypotrichosis) on the scalp beginning in infancy. This hair is usually coarse, dry, and tightly curled (often described as woolly hair). Scalp hair may also be lighter in color than expected and is fragile and easily broken. Affected individuals often cannot grow hair longer than a few inches. The eyebrows, eyelashes, and other body hair may be sparse as well. Over time, the hair problems can remain stable or progress to complete scalp hair loss (alopecia) and a decrease in body hair.\n\nRarely, people with autosomal recessive hypotrichosis have skin problems affecting areas with sparse hair, such as redness (erythema), itchiness (pruritus), or missing patches of skin (erosions) on the scalp. In areas of poor hair growth, they may also develop bumps called hyperkeratotic follicular papules that develop around hair follicles, which are specialized structures in the skin where hair growth occurs.
8q22.1 microdeletion syndrome
MedGen UID:
334165
Concept ID:
C1842464
Disease or Syndrome
Nablus mask-like facial syndrome (NMLFS) is a rare entity defined by distinctive facial features, including blepharophimosis, tight-appearing glistening facial skin, an abnormal hair pattern with an upswept frontal hairline, sparse arched eyebrows, flat and broad nose, long philtrum, distinctive ears, and a happy demeanor (summary by Jain et al., 2010).
Hypotrichosis 6
MedGen UID:
335812
Concept ID:
C1842839
Disease or Syndrome
Hypotrichosis-6 (HYPT6) is a localized autosomal recessive hypotrichosis characterized by fragile hairs that break easily, leaving short, sparse scalp hairs. The disorder affects the trunk and extremities as well as the scalp, and the eyebrows and eyelashes may also be involved, whereas beard, pubic, and axillary hairs are largely spared. In addition, patients can develop hyperkeratotic follicular papules, erythema, and pruritus in affected areas. In some patients with congenital hypotrichosis, monilethrix-like hairs showing elliptical nodes have been observed (summary by Schaffer et al., 2006). Genetic Heterogeneity of Autosomal Recessive Localized Hypotrichosis LAH2 (HYPT7; 604379) is caused by mutation in the LIPH gene (607365) on chromosome 3q27, and LAH3 (HYPT8; 278150) is caused by mutation in the LPAR6 (P2RY5) gene (609239) on chromosome 13q14.12-q14.2. See also hypotrichosis and recurrent skin vesicles (613102), which is caused by mutation in the DSC3 gene (600271).

Rapadilino syndrome
MedGen UID:
336602
Concept ID:
C1849453
Disease or Syndrome
The RAPADILINO syndrome is an autosomal recessive disorder characterized by short stature, radial ray defects and other malformations, and infantile diarrhea. The acronym is derived from hallmark features: RA for radial; PA for both absent/hypoplastic patellas and cleft/highly arched palate; DI for diarrhea, as well as dislocated joints; LI for little size and limb malformations; and NO for long, slender nose and normal intelligence. RAPADILINO belongs to the Finnish disease heritage (Kaariainen et al., 1989; Siitonen et al., 2003).

Arrhythmogenic cardiomyopathy with wooly hair and keratoderma
MedGen UID:
340124
Concept ID:
C1854063
Disease or Syndrome
Dilated cardiomyopathy with woolly hair and keratoderma (DCWHK) is characterized by the presence of woolly or sparse hair from birth. Some patients exhibit fragile skin with blisters/erosions after minor mechanical trauma, with hyperkeratosis and epidermolytic keratoderma developing in early childhood. Cardiomyopathy may become apparent in the first decade of life, and early death due to heart failure has been reported, but patients may remain asymptomatic into the fourth decade of life. Some patients exhibit an arrhythmogenic form of cardiomyopathy, with sudden death in early adulthood (Carvajal-Huerta, 1998; Whittock et al., 2002; Alcalai et al., 2003; Uzumcu et al., 2006). Another syndrome involving cardiomyopathy, woolly hair, and keratoderma (Naxos disease; 601214) is caused by mutation in the plakoglobin gene (JUP; 173325). Also see 610476 for a similar disorder caused by homozygous mutation in the DSC2 gene (125645). Dilated cardiomyopathy with woolly hair, keratoderma, and tooth agenesis (DCWHKTA; 615821) is caused by heterozygous mutation in DSP. An isolated form of striated PPK (PPKS2; 612908) is also caused by heterozygous mutation in DSP. Reviews In a review of cardiocutaneous syndromes and arrhythmogenic cardiomyopathy, Sen-Chowdhry and McKenna (2014) stated that although the cardiac component of Carvajal syndrome was originally considered dilated cardiomyopathy, many of its features resemble those of arrhythmogenic cardiomyopathy (see 607450). In addition, they noted that different disease subtypes have been found to coexist within the same kindred, suggesting a role for modifier genes and/or environmental influences.
Cerebrooculonasal syndrome
MedGen UID:

Congenital Abnormality
EEM syndrome (EEMS) denotes a disorder characterized by ectodermal dysplasia, ectrodactyly, and macular dystrophy. The ectodermal dysplasia consists of hypotrichosis affecting scalp hair, eyebrows, and eyelashes, with partial anodontia. Different degrees of absence deformities as well as syndactyly have been described, the hands often being more severely affected than the feet. The retinal lesion appears as a central geographic atrophy of the retinal pigment epithelium and choriocapillary layer of the macular area with coarse hyperpigmentations and sparing of the larger choroidal vessels (summary by Kjaer et al., 2005).
Dyskeratosis congenita, autosomal recessive 1
MedGen UID:
341705
Concept ID:
C1857144
Disease or Syndrome

The phenotypic spectrum of telomere biology disorders is broad and includes individuals with classic dyskeratosis congenita (DC) as well as those with very short telomeres and an isolated physical finding. Classic DC is characterized by a triad of dysplastic nails, lacy reticular pigmentation of the upper chest and/or neck, and oral leukoplakia, although this may not be present in all individuals. People with DC/TBD are at increased risk for progressive bone marrow failure (BMF), myelodysplastic syndrome or acute myelogenous leukemia, solid tumors (usually squamous cell carcinoma of the head/neck or anogenital cancer), and pulmonary fibrosis. Other findings can include eye abnormalities (epiphora, blepharitis, sparse eyelashes, ectropion, entropion, trichiasis), taurodontism, liver disease, gastrointestinal telangiectasias, and avascular necrosis of the hips or shoulders. Although most persons with DC/TBD have normal psychomotor development and normal neurologic function, significant developmental delay is present in both forms; additional findings include cerebellar hypoplasia (Hoyeraal Hreidarsson syndrome) and bilateral exudative retinopathy and intracranial calcifications (Revesz syndrome and Coats plus syndrome).

Hypotrichosis 4
MedGen UID:
413053
Concept ID:
C2750815
Disease or Syndrome
Hypotrichosis-4 (HYPT4), also known as Marie Unna hereditary hypotrichosis-1 (MUHH1), is an autosomal dominant form of hair loss characterized by the absence or scarcity of scalp hair, eyebrows, and eyelashes at birth. Coarse, wiry hair begins to grow during childhood. Around puberty, progressive hair loss occurs in the affected patients. Although the disorder has the potential to affect all hair shafts, progressive and patterned alopecia of the scalp is the main manifestation of the disorder (summary by Mansur et al., 2010). For a discussion of genetic heterogeneity of nonsyndromic hypotrichosis, see 605389. Genetic Heterogeneity of Marie Unna Hereditary Hypotrichosis See also MUHH2 (HYPT5; 612841), caused by heterozygous mutation in the EPS8L3 gene (614989) on chromosome 1p13.

Frontonasal dysplasia - severe microphthalmia - severe facial clefting syndrome
MedGen UID:
462056
Concept ID:
C3150706
Disease or Syndrome
Life expectancy of affected individuals depends on the severity of the malformations and whether or not surgical intervention can improve associated health problems, such as breathing and feeding problems caused by the facial clefts.\n\nFrontonasal dysplasia is a condition that results from abnormal development of the head and face before birth. People with frontonasal dysplasia have at least two of the following features: widely spaced eyes (ocular hypertelorism); a broad nose; a slit (cleft) in one or both sides of the nose; no nasal tip; a central cleft involving the nose, upper lip, or roof of the mouth (palate); incomplete formation of the front of the skull with skin covering the head where bone should be (anterior cranium bifidum occultum); or a widow's peak hairline.\n\nOther features of frontonasal dysplasia can include additional facial malformations, absence or malformation of the tissue that connects the left and right halves of the brain (the corpus callosum), and intellectual disability.\n\nThere are at least three types of frontonasal dysplasia that are distinguished by their genetic causes and their signs and symptoms. In addition to the features previously described, each type of frontonasal dysplasia is associated with other distinctive features. Individuals with frontonasal dysplasia type 1 typically have abnormalities of the nose, a long area between the nose and upper lip (philtrum), and droopy upper eyelids (ptosis). Individuals with frontonasal dysplasia type 2 can have hair loss (alopecia) and an enlarged opening in the two bones that make up much of the top and sides of the skull (enlarged parietal foramina). Males with this form of the condition often have genital abnormalities. Features of frontonasal dysplasia type 3 include eyes that are missing (anophthalmia) or very small (microphthalmia) and low-set ears that are rotated backward. Frontonasal dysplasia type 3 is typically associated with the most severe facial abnormalities, but the severity of the condition varies widely, even among individuals with the same type.

Cranioectodermal dysplasia (CED) is a ciliopathy with skeletal involvement (narrow thorax, shortened proximal limbs, syndactyly, polydactyly, brachydactyly), ectodermal features (widely spaced hypoplastic teeth, hypodontia, sparse hair, skin laxity, abnormal nails), joint laxity, growth deficiency, and characteristic facial features (frontal bossing, low-set simple ears, high forehead, telecanthus, epicanthal folds, full cheeks, everted lower lip). Most affected children develop nephronophthisis that often leads to end-stage kidney disease in infancy or childhood, a major cause of morbidity and mortality. Hepatic fibrosis and retinal dystrophy are also observed. Dolichocephaly, often secondary to sagittal craniosynostosis, is a primary manifestation that distinguishes CED from most other ciliopathies. Brain malformations and developmental delay may also occur.

Hypotrichosis 8
MedGen UID:
481100
Concept ID:
C3279470
Disease or Syndrome
Hypotrichosis simplex refers to a group of hereditary isolated alopecias characterized by diffuse and progressive hair loss, usually beginning in early childhood (Pasternack et al., 2008). Localized autosomal recessive hypotrichosis (LAH) is characterized by fragile hairs that break easily, leaving short, sparse scalp hairs. The disorder affects the trunk and extremities as well as the scalp, and the eyebrows and eyelashes may also be involved, whereas beard, pubic, and axillary hairs are largely spared. In addition, patients can develop hyperkeratotic follicular papules, erythema, and pruritus in affected areas (summary by Schaffer et al., 2006). Woolly hair (WH) refers to a group of hair shaft disorders that are characterized by fine and tightly curled hair. Compared to normal curly hair that is observed in some populations, WH grows slowly and stops growing after a few inches. Under light microscopy, WH shows some structural anomalies, including trichorrhexis nodosa and tapered ends (summary by Petukhova et al., 2009). Several families have been reported in which some affected individuals exhibit features of hypotrichosis and others have woolly scalp hair (Khan et al., 2011). Woolly hair is also a feature of several syndromes, such as Naxos disease (601214) and cardiofaciocutaneous syndrome (115150) (Petukhova et al., 2009), or the palmoplantar keratoderma and cardiomyopathy syndrome (601214) (Carvajal-Huerta, 1998). Genetic Heterogeneity of Hypotrichosis and Woolly Hair For a discussion of genetic heterogeneity of nonsyndromic hypotrichosis, see HYPT1 (605389). For a discussion of genetic heterogeneity of localized hypotrichosis, see LAH1 (HYPT6; 607903). Another form of autosomal recessive woolly hair with or without hypotrichosis (ARWH2; 604379) is caused by mutation in the LIPH gene (607365) and is allelic to autosomal recessive localized hypotrichosis (LAH2). ARWH3 (616760) is caused by mutation in the KRT25 gene (616646) on chromosome 17q21. An autosomal dominant form of woolly hair with hypotrichosis (HYPT13; 615896) is caused by mutation in the KRT71 gene (608245) on chromosome 12q13. Another autosomal dominant form of woolly hair (ADWH; 194300) with normal hair density is caused by mutation in the KRT74 gene (608248) on chromosome 12q13, and is allelic to an autosomal dominant form of hypotrichosis simplex of the scalp (HYPT3; 613981) as well as an ectodermal dysplasia of the hair/nail type (ECTD7; 614929).

Disease or Syndrome
Hereditary hypotrichosis simplex (HHS) is a rare form of nonsyndromic hereditary hypotrichosis without characteristic hair shaft anomalies. Affected individuals typically show normal hair at birth, but hair loss and thinning of the hair shaft start during early childhood and progress with age. HHS can be largely divided into 2 forms: the scalp-limited form (e.g., 146520) and the generalized form, such as HYPT1, in which all body hair is affected. HHS is characterized by progressive hair follicle miniaturization, which is a typical feature of androgenetic alopecia (see 109200). HHS can be inherited either as an autosomal dominant or autosomal recessive trait (e.g., HYPT8, 278150) (summary by Shimomura et al., 2010).
