Summaries for Ectodermal Dysplasia 12, Hypohidrotic/hair/tooth/nail Type

OMIM : 57 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 (summary by Cluzeau et al., 2011). For a discussion of genetic heterogeneity of hypohidrotic/anhidrotic ectodermal dysplasia, see 305100. (617337)

MalaCards based summary : Ectodermal Dysplasia 12, Hypohidrotic/hair/tooth/nail Type, is also known as ectd12. An important gene associated with Ectodermal Dysplasia 12, Hypohidrotic/hair/tooth/nail Type is KDF1 (Keratinocyte Differentiation Factor 1). Affiliated tissues include skin and eye, and related phenotypes are short philtrum and natal tooth

UniProtKB/Swiss-Prot : 75 Ectodermal dysplasia 12, hypohidrotic/hair/tooth/nail type: A form of ectodermal dysplasia, a disorder due to abnormal development of two or more ectodermal structures. ECTD12 is an autosomal dominant, hypohidrotic form characterized by sparse hair (atrichosis or hypotrichosis), abnormal or missing teeth, and the inability to sweat due to defective development of sweat glands.
