The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_000503.6(EYA1):c.124+3061G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene EYA1 is a cancer driver gene (CancerMine: 2 driver citations). The variant allele was found at a cumulative frequency of 0.835 (AC=127,075) in the gnomAD database across 152,210 control chromosomes, including 53,098 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.864. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
