RCV000039721 | SCV000063410 | uncertain significance | not specified | 2016-12-22 | criteria provided, single submitter | clinical testing | The p.Pro1044Leu variant in PCDH15 has now been identified by our laboratory in 2 individuals with hearing loss, but neither of them had a variant affecting the other copy of PCDH15. This variant has been identified in 0.08% (26/30896) of S outh Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad .broadinstitute.org/; dbSNP rs397517455). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogen ic role. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinica l significance of the p.Pro1044Leu variant is uncertain. |

RCV001050722 | SCV001214843 | uncertain significance | not provided | 2022-06-05 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1044 of the PCDH15 protein (p.Pro1044Leu). This variant is present in population databases (rs397517455, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with PCDH15-related conditions. ClinVar contains an entry for this variant (Variation ID: 46462). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

Ambry Genetics | RCV004018893 | SCV004998829 | uncertain significance | Inborn genetic diseases | 2023-09-23 | criteria provided, single submitter | clinical testing | The c.3131C>T (p.P1044L) alteration is located in exon 24 (coding exon 23) of the PCDH15 gene. This alteration results from a C to T substitution at nucleotide position 3131, causing the proline (P) at amino acid position 1044 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
