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 submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Apr 25, 2016	Variant summary: The PCDH15 c.55T>G variant affects a non-conserved nucleotide, resulting in amino acid change from Ser to Ala. 3/4 in-silico tools predict benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 25808/118352 control chromosomes (3055 homozygotes) at a frequency of 0.2180614, which is about 69 times of the maximal expected frequency of a pathogenic PCDH15 allele (0.0031623), suggesting this variant is a benign polymorphism. This variant is reported in USH patients without evidence for causality and authors listed the variant as a frequent SNP. In addition, one reputable clinical laboratory via ClinVar classified this variant as benign. Taken together, this variant was classified as Benign. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
