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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM1: In a chain Ectodysplasin-A receptor-associated adapter protein (size 214) in uniprot entity EDAD_HUMAN there are 10 pathogenic changes around while only 3 benign (77%) in NM_145861.4
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 9 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 1.1424 (below the threshold of 3.09). Trascript score misZ: 1.2505 (below the threshold of 3.09). GenCC associations: The gene is linked to autosomal recessive hypohidrotic ectodermal dysplasia, autosomal dominant hypohidrotic ectodermal dysplasia, tooth agenesis, ectodermal dysplasia 11B, hypohidrotic/hair/tooth type, autosomal recessive, ectodermal dysplasia 11A, hypohidrotic/hair/tooth type, autosomal dominant.

Collection Method: clinical testing

The c.95A>G (p.D32G) alteration is located in exon 2 (coding exon 2) of the EDARADD gene. This alteration results from a A to G substitution at nucleotide position 95, causing the aspartic acid (D) at amino acid position 32 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
