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]

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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

p.Asn419Ser variant in exon 11 of PCDH15: This variant is not expected to have c linical significance because it has been identified in 0.136% (6/4406) of Afric an American chromosomes by the NHLBI Exome Sequencing Project, and in 1.639% (2/ 122) of African American chromosomes and in 0.568% (1/176) of Nigerian chromosom es by the 1000 Genomes Project (http://evs.gs.washington.edu/EVS/; dbSNP rs14382 7620). In addtion, asparaginine (Asn) at position 419 is not well conserved in m ammals or evolutionarily distant species with many fish carrying a serine (Ser) at this position and computational prediction tools do not suggest a high likeli hood of impact to the protein. which supports that variants at this position may be tolerated. -
