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]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 8-71215476-GTAGTTGT-G is Pathogenic according to our data. Variant chr8-71215476-GTAGTTGT-G is described in ClinVar as [Pathogenic]. Clinvar id is 7944.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr8-71215476-GTAGTTGT-G is described in Lovd as [Pathogenic].
