Hearing Loss VCEP

The c.5131 (p.Val1711Ile) variant has been identified in 0.3% (51/19534 CI 95%) of East Asian alleles in gnomAD (BS1). This variant was observed in 1 patient with Usher syndrome, without a second variant in CDH23 (PMID: 25333064). Computational prediction analysis using the metapredictor tool REVEL produced a score of .17; this combined with the presence of the isoleucine amino acid at position 1711 in 5 organisms including 3 mammals in UCSC suggests that the variant may not impact the protein (BP4). In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel: BS1, BP4.

BS1

Present in .3% (51/19534 CI 95%) of South Asian alleles in gnomAD.

BP4

REVEL: .17, which does not meet the cut off for BP4 however the amino acid change is present in 5 organisms in UCSC including 3 mammals. After expert review BP4 was applied.
