Invitae | RCV001070437 | SCV001235667 | uncertain significance | not provided | 2021-08-27 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine with isoleucine at codon 1539 of the PCDH15 protein (p.Asn1539Ile). The asparagine residue is moderately conserved and there is a large physicochemical difference between asparagine and isoleucine. This variant is present in population databases (rs780662896, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with PCDH15-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The isoleucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
