General annotation (Comments)

Function	Receptor for EDA isoform A1, but not for EDA isoform A2. Mediates the activation of NF-kappa-B and JNK. May promote caspase-independent cell death.
Subunit structure	Binds to EDARADD. Associates with TRAF1, TRAF2, TRAF3 and NIK. Ref.4 Ref.5
Subcellular location	Membrane; Single-pass type I membrane protein Probable.
Tissue specificity	Detected in fetal kidney, lung, skin and cultured neonatal epidermal keratinocytes. Not detected in lymphoblast and fibroblast cell lines.
Developmental stage	Found in craniofacial tissues from embryonic day 42-53. Expressed in fetal skin 11 and 15 weeks after gestation.
Polymorphism	Genetic variation in EDAR is associated with hair morphology type 1 (HRM1) [MIM:612630]; also called variation in hair thickness. Besides skin color and facial features, hair morphology is one of the most distinctive traits among human populations, and classical classification of human population is based on such visible traits.
Involvement in disease	Defects in EDAR are a cause of ectodermal dysplasia anhidrotic (EDA) [MIM:224900]; also known ectodermal dysplasia hypohidrotic autosomal recessive (HED). Ectodermal dysplasia defines a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. EDA is characterized by sparse hair (atrichosis or hypotrichosis), abnormal or missing teeth and the inability to sweat due to the absence of sweat glands. Ref.4 Ref.1 Defects in EDAR are the cause of ectodermal dysplasia type 3 (ED3) [MIM:129490]; also known as ectodermal dysplasia hypohidrotic autosomal dominant or EDA3. ED3 is an autosomal dominant condition characterized by hypotrichosis, abnormal or missing teeth, and hypohidrosis due to the absence of sweat glands. Ref.1 Ref.9
Sequence similarities	Contains 1 death domain. Contains 3 TNFR-Cys repeats.
