EVIDENCE SUMMARY |
The EYA1 gene has been associated with autosomal dominant Branchio-oto-renal syndrome using the ClinGen Clinical Validity Framework as of 10/17/17. This association was made using case-level data. Multiple missense, nonsense, frameshift and splice-site variants have been reported in humans. EYA1 was first associated with this disease in humans as early as 1997 (Abdelhak et al.). Nine probands, familial and de novo, were scored for this curation (9020840, 18220287, 19206155). More evidence is available in the literature, but the maximum score for genetic evidence and experimental evidence has been reached. This gene-disease association is supported by a spontaneous mouse model, a Xenopus model and a rescue in Xenopus oocytes (10072433, 19951260). In summary, EYA1 is definitively associated with autosomal dominant Branchio-oto-renal syndrome. This has been repeatedly demonstrated in both the research and clinical diagnostic settings, and has been upheld over time. This classification was approved by the ClinGen Hearing Loss Working Group on 11/21/17.
