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]

PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The PCDH15 c.1028G>A variant is predicted to result in the amino acid substitution p.Arg343Lys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.041% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

p.Arg343Lys in exon 10 of PCDH155: This variant is not expected to have clinical significance because the Arg residue at position 343 is not well conserved acro ss distant species, computational analysis do not suggest a high likelihood of i mpact to the protein, and it has been identified in 50/126580 European chromosom es by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs141169746). Furthermore, it has been identified in cis with a pathogeni c variant in PCDH15 in an individual with Usher syndrome. -
