Genes affected

EYA1 (HGNC:3519): (EYA transcriptional coactivator and phosphatase 1) This gene encodes a member of the eyes absent (EYA) family of proteins. The encoded protein may play a role in the developing kidney, branchial arches, eye, and ear. Mutations of this gene have been associated with branchiootorenal dysplasia syndrome, branchiootic syndrome, and sporadic cases of congenital cataracts and ocular anterior segment anomalies. A similar protein in mice can act as a transcriptional activator. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Dec 2013]

EYA1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.106156796).

The p.Ile30Val variant in EYA1 has not been previously reported in individuals w ith hearing loss or in large population studies. Computational prediction tools and conservation analysis suggest that the variant may not impact the protein, t hough this information is not predictive enough to rule out pathogenicity. In su mmary, the clinical significance of the p.Ile30Val variant is uncertain. -
