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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Gly135Ser variant in EYA1 has been reported in at least Japanese individua l with hearing loss (Miyagawa 2013) and has also been reported in ClinVar (Varia tion ID#225351). This variant has been identified in 0.06% (11/17210) of East As ian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadi nstitute.org; dbSNP rs747476629); however the frequency is not high enough to ru le out a pathogenic role. Computational prediction tools and conservation analys is suggest that the p.Gly135Ser variant may impact the protein, though this info rmation is not predictive enough to determine pathogenicity. In summary, the cli nical significance of the p.Gly135Ser variant is uncertain. ACMG/AMP Criteria ap plied: PP3 -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
