Labcorp Genetics (formerly Invitae), Labcorp RCV000628840 SCV000749747 uncertain significance Hypertrophic cardiomyopathy 2017-08-28 criteria provided, single submitter clinical testing This sequence change replaces proline with threonine at codon 535 of the JPH2 protein (p.Pro535Thr). The proline residue is moderately conserved and there is a small physicochemical difference between proline and threonine. While this variant is not present in population databases, the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with JPH2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
