Summaries for Ectodermal Dysplasia 4, Hair/nail Type

UniProtKB/Swiss-Prot : 75 Ectodermal dysplasia 4, hair/nail type: A form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia. ECTD4 is characterized by complete alopecia, hypotricosis and nail dystrophy in all digits. There is no evidence of any other abnormality. Inheritance can be autosomal dominant or recessive.

MalaCards based summary : Ectodermal Dysplasia 4, Hair/nail Type, also known as ectodermal dysplasia, 'pure' hair-nail type, is related to lacrimal duct obstruction and ectodermal dysplasia. An important gene associated with Ectodermal Dysplasia 4, Hair/nail Type is KRT85 (Keratin 85), and among its related pathways/superpathways is Keratinization. Affiliated tissues include skin, and related phenotypes are absent eyelashes and alopecia

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. Ectodermal dysplasia of the hair/nail type is a rare congenital condition characterized by hypotrichosis and nail dystrophy without nonectodermal or other ectodermal manifestations. (602032)
