High match ECTODERMAL DYSPLASIA 10B, HYPOHIDROTIC/HAIR/TOOTH TYPE, AUTOSOMAL RECESSIVE; ECTD10B

Some ectodermal dysplasias are here classified as congenital disorders characterized by abnormal development in 2 or more ectodermal structures (hair, nails, teeth, and sweat glands) without other systemic findings.Hypohidrotic, or anhidrotic, ectodermal dysplasia is characterized by a triad of signs comprising sparse hair (hypotrichosis), abnormal or missing teeth (anodontia or hypodontia), and inability to sweat (anhidrosis or hypohidrosis). Typical clinical manifestations also include dryness of the skin, eyes, airways, and mucous membranes presumably due to the defective development of several exocrine glands. Hypohidrotic ectodermal dysplasia can be associated with dysmorphic features (forehead bumps, rings under the eyes, everted nose, and prominent lips) and occasionally with absent nipples (summary by Cluzeau et al., 2011).For a discussion of genetic heterogeneity of hypohidrotic/anhidrotic ectodermal dysplasia, see {305100}.

Coffin-Siris syndrome-7 is an autosomal dominant neurodevelopmental disorder characterized by global developmental delay with mild to moderate intellectual disability, speech impairment, behavioral abnormalities, poor overall growth, coarse facial features, and hypoplastic fifth toenails (summary by Vasileiou et al., 2018).For a general phenotypic description and a discussion of genetic heterogeneity of Coffin-Siris syndrome, see CSS1 (OMIM ).

Axenfeld-Rieger syndrome (ARS) is a generic term used to designate overlapping genetic disorders, in which the major physical condition is anterior segment dysgenesis of the eye. Patients with ARS may also present with multiple variable congenital anomalies.

High match X-LINKED HYPOHIDROTIC ECTODERMAL DYSPLASIA

Some ectodermal dysplasias are here classified as congenital disorders characterized by abnormal development in 2 or more ectodermal structures (hair, nails, teeth, and sweat glands) without other systemic findings.Hypohidrotic, or anhidrotic, ectodermal dysplasia (HED/EDA) is characterized by a triad of signs comprising sparse hair (hypotrichosis), abnormal or missing teeth (anodontia or hypodontia), and inability to sweat (anhidrosis or hypohidrosis). Typical clinical manifestations also include dryness of the skin, eyes, airways, and mucous membranes presumably due to the defective development of several exocrine glands. Hypohidrotic ectodermal dysplasia can be associated with dysmorphic features (forehead bumps, rings under the eyes, everted nose, and prominent lips) and occasionally with absent nipples. Ectodermal dysplasia-1, due to mutation in the EDA gene, is the most frequent form of hypohidrotic ectodermal dysplasia (summary by Cluzeau et al., 2011).

High match ABLEPHARON MACROSTOMIA SYNDROME

Ablepharon macrostomia syndrome is an extremely rare multiple congenital malformation syndrome characterized by the association of ablepharon, macrostomia, abnormal external ears, syndactyly of the hands and feet, skin findings (such as dry and coarse skin or redundant folds of skin), absent or sparse hair, genital malformations and developmental delay (in 2/3 of cases). Other reported manifestations include malar hypoplasia, absent or hypoplastic nipples, umbilical abnormalities and growth retardation. It is a mainly sporadic disorder, although a few familial cases having been reported, and it displays significant clinical overlap with Fraser syndrome (see this term).

Cranioectodermal dysplasia (CED), also known as Sensenbrenner syndrome, is a rare autosomal recessive heterogeneous ciliopathy that is primarily characterized by skeletal abnormalities, including craniosynostosis, narrow rib cage, short limbs, and brachydactyly, and ectodermal defects. Nephronophthisis leading to progressive renal failure, hepatic fibrosis, heart defects, and retinitis pigmentosa have also been described (summary by Arts et al., 2011).For a discussion of genetic heterogeneity of cranioectodermal dysplasia, see CED1 (OMIM ).
