Genes affected
EDARADD (HGNC:14341): (EDAR associated via death domain) This gene was identified by its association with ectodermal dysplasia, a genetic disorder characterized by defective development of hair, teeth, and eccrine sweat glands. The protein encoded by this gene is a death domain-containing protein, and is found to interact with EDAR, a death domain receptor known to be required for the development of hair, teeth and other ectodermal derivatives. This protein and EDAR are coexpressed in epithelial cells during the formation of hair follicles and teeth. Through its interaction with EDAR, this protein acts as an adaptor, and links the receptor to downstream signaling pathways. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 8 of the EDARADD protein (p.Gln8Glu). This variant is present in population databases (rs144687140, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with EDARADD-related conditions. ClinVar contains an entry for this variant (Variation ID: 1967978). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Possibly Damaging". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
