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]

This sequence change creates a premature translational stop signal (p.Arg77*) in the EYA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EYA1 are known to be pathogenic (PMID: 10464653, 18220287). This variant is present in population databases (no rsID available, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with clinical features of EYA1-related conditions (PMID: 33240318). ClinVar contains an entry for this variant (Variation ID: 459254). For these reasons, this variant has been classified as Pathogenic. -
