Genes affected

PCDH15 (HGNC:14674): (protocadherin related 15) This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. It plays an essential role in maintenance of normal retinal and cochlear function. Mutations in this gene result in hearing loss and Usher Syndrome Type IF (USH1F). Extensive alternative splicing resulting in multiple isoforms has been observed in the mouse ortholog. Similar alternatively spliced transcripts are inferred to occur in human, and additional variants are likely to occur. [provided by RefSeq, Dec 2008]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The G1543S variant in the PCDH15 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The G1543S variant is observed in 37/9726 (0.38%) alleles from individuals of African background in the ExAC dataset (Lek et al., 2016). The G1543S variant is a non-conservative amino acid substitution, which occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret G1543S as a variant of uncertain significance. -
