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]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is not expected to have clinical significance because this residue is not highly conserved across species and this is not a significant biochemical change. In addition, this variant has been entered 6 times in dbSNP with a 3.6% (6/168) allele frequency in the West African population (rs61735473). Furthermo re, this variant has been identified by our laboratory in 2/15 (13.3%) Black pro bands. -

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. -

Variant summary: The PCDH15 c.1360G>A (p.Val454Ile) variant involves the alteration of a non-conserved nucleotide. 3/4 in silico tools predict a benign outcome for this variant. This variant was found in 397/121340 control chromosomes (including 6 homozygotes), predominantly observed in the African subpopulation at a frequency of 0.0347943 (362/10404). This frequency is about 11 times the estimated maximal expected allele frequency of a pathogenic PCDH15 variant (0.0031623), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories have classified this variant as benign. Taken together, this variant is 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. -
