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]

Benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 10, 2017p.Ile1519Val in exon 37 of PCDH15: This variant is not expected to have clinical significance because it has been identified in 0.65% (219/33858) of Latino chro mosomes including 1 homozygote by the Genome Aggregation Consortium (gnomAD, htt p://gnomad.broadinstitute.org; dbSNP rs201855435). -
Uncertain significance, criteria provided, single submitterclinical testingGeneDxMar 13, 2017The I1519V variant in the PCDH15 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The I1519V variant is observed in 71/11576 (0.61%) alleles from individuals of Latino background in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The I1519V variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function.We interpret I1519V as a variant of uncertain significance. -
