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]

The c.509G>A (p.R170Q) alteration is located in exon 6 (coding exon 6) of the EDARADD gene. This alteration results from a G to A substitution at nucleotide position 509, causing the arginine (R) at amino acid position 170 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with a EDARADD-related disease. This variant is present in population databases (rs757261515, ExAC 0.01%). This sequence change replaces arginine with glutamine at codon 170 of the EDARADD protein (p.Arg170Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. -
