Disease[EDA_HUMAN] Defects in EDA are the cause of ectodermal dysplasia 1, hypohidrotic, X-linked (XHED) [MIM:305100]; also known as Christ-Siemens-Touraine syndrome or X-linked hypohidrotic ectodermal dysplasia (XLHED). Ectodermal dysplasia defines a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. XHED is a disease characterized by sparse hair (atrichosis or hypotrichosis), abnormal or missing teeth and the inability to sweat due to the absence of sweat glands. XHED is the most common form of over 150 clinically distinct ectodermal dysplasias.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] Defects in EDA are the cause of tooth agenesis selective X-linked type 1 (STHAGX1) [MIM:313500]. A form of selective tooth agenesis, a common anomaly characterized by the congenital absence of one or more teeth. Selective tooth agenesis without associated systemic disorders has sometimes been divided into 2 types: oligodontia, defined as agenesis of 6 or more permanent teeth, and hypodontia, defined as agenesis of less than 6 teeth. The number in both cases does not include absence of third molars (wisdom teeth).[24] [25] Function[EDA_HUMAN] Seems to be involved in epithelial-mesenchymal signaling during morphogenesis of ectodermal organs.
