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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The Leu583Pro variant in EYA1 has been identified in two probands with clinical features of Branchio-oto-renal syndrome (BOR), was absent from 85 controls, and segregated with clinical features in one affected family member (Rickard 2000, L MM unpublished data). In addition, this residue is conserved across species, and computational analyses (biochemical amino acid properties, homology, PolyPhen2, SIFT) suggest that the variant may impact the protein. In summary, this variant is likely to be pathogenic. -
