| Invitae | RCV002232783 | SCV000761037 | uncertain significance | Familial hypocalciuric hypercalcemia; Autosomal dominant hypocalcemia 1 | 2017-10-15 | 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with CASR-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with glutamine at codon 461 of the CASR protein (p.Leu461Gln). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and glutamine. |

RCV003420120 | SCV004114562 | uncertain significance | CASR-related condition | 2022-11-02 | criteria provided, single submitter | clinical testing | The CASR c.1382T>A variant is predicted to result in the amino acid substitution p.Leu461Gln. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. A different amino acid substitution as this position (p.Leu461Gln) has been reported in two individuals with familial hypocalciuric hypercalcemia (Hannan et al 2012. PubMed ID: 22422767). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
