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: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.3502-14dupT variant is classified as benign because it has been identified in 26.4% of total chromosomes, including 9873 homozygotes, by gnomAD (http://gn omad-beta.broadinstitute.org/) -

GeneDx

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The PCDH15 c.3502-14dupT variant involves the duplication of an intronic nucleotide. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 29147/114904 control chromosomes (3844 homozygotes) at a frequency of 0.2536639, which is approximately 80 times the estimated maximal expected allele frequency of a pathogenic PCDH15 variant (0.0031623), strong evidence that this variant is a benign polymorphism. In addition, one clinical diagnostic laboratory/reputable database has classified this variant as benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -
