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]

Review Status: criteria provided, single submitter

Collection Method: curation

The p.Thr1373Ile variant in PCDH15 has been reported in 2 individuals, in the compound heterozygous state, with Usher syndrome type 1F (PMID: 23767834) and has been identified in 0.02% (3/18394) of East Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP ID: rs756490783). Although this variant has been seen in the general population in a heterozygous state, its frequency is not high enough to rule out a pathogenic role. This variant has also been reported in ClinVar (Variation ID#: 556004) and has been interpreted as a variant of uncertain significance by Counsyl. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Thr1373Ile variant is uncertain. ACMG/AMP Criteria applied: none (Richards 2015). -
