ClinGen Hearing Loss Variant Curation Expert Panel RCV001171528 SCV001334313 uncertain significance Usher syndrome 2020-03-18 reviewed by expert panel curation The c.3491G>A (p.Arg1164Gln) variant in MYO7A was present in 0.003519% (1/28416) of South Asian chromosomes in gnomAD, which is a low enough frequency to apply PM2 based on the thresholds defined by the ClinGen Hearing Loss Expert Panel for autosomal recessive hearing loss (PM2). This variant was observed in 1 proband with hearing loss and retinitis pigmentosa and another pathogenic variant in MYO7A in trans (PM3; LMM internal data, SCV000272160.2). However, this individual presented with another possible genetic explanation of retinitis pigmentosa (PP4 not met). The REVEL computational prediction analysis tool produced a score of 0.94, which is above the threshold necessary to apply PP3. In summary, the clinical significance of this variant is uncertain based on ACMG/AMP criteria applied as specified by the Hearing Loss Expert Panel (PM2, PM3, PP3).
