Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001779485 SCV002014975 uncertain significance not specified 2021-10-19 criteria provided, single submitter clinical testing Variant summary: CASR c.2448C>G (p.Ile816Met) results in a conservative amino acid change located in the GPCR family 3, C-terminal domain (IPR017978) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251330 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.2448C>G in individuals affected with Familial Hypocalciuric Hypercalcemia and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV001868824 SCV002278029 uncertain significance Familial hypocalciuric hypercalcemia; Autosomal dominant hypocalcemia 1 2021-12-15 criteria provided, single submitter clinical testing 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. 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: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1321391). This variant has not been reported in the literature in individuals affected with CASR-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 816 of the CASR protein (p.Ile816Met).
