Labcorp Genetics (formerly Invitae), Labcorp RCV002232884 SCV000816731 uncertain significance Familial hypocalciuric hypercalcemia; Autosomal dominant hypocalcemia 1 2020-06-30 criteria provided, single submitter clinical testing This sequence change replaces arginine with glutamine at codon 1041 of the CASR protein (p.Arg1041Gln). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and glutamine. The frequency data for this variant in the population databases is considered 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 CASR-related disease. 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 glutamine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. 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.
