The p.Val861Met variant in PCDH15 has been reported in the heterozygous state in one individual with Usher syndrome who did not carry a variant on the other all ele (Bujakowska 2014). It has also been identified in 0.09% (111/126546) of Euro pean chromosomes and 0.13% (46/34366) of Latino chromosomes by the Genome Aggreg ation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs142512524); th ough this frequency is not high enough to rule out a pathogenic role. Computatio nal prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of t he p.Val861Met variant is uncertain. -
Autosomal recessive nonsyndromic hearing loss 23 Uncertain:1

Usher syndrome type 1 Uncertain:1
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. -
