Invitae RCV000472371 SCV000550981 uncertain significance Familial hypocalciuric hypercalcemia; Autosomal dominant hypocalcemia 1 2023-08-17 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with CASR-related conditions. ClinVar contains an entry for this variant (Variation ID: 410344). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. This variant is present in population databases (rs201091657, gnomAD 0.006%). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 217 of the CASR protein (p.Asp217Asn).
Illumina Laboratory Services, Illumina RCV001144946 SCV001305570 uncertain significance Neonatal severe primary hyperparathyroidism 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.

Ambry Genetics RCV002365648 SCV002659161 uncertain significance Inborn genetic diseases; Nephrolithiasis/nephrocalcinosis 2021-09-16 criteria provided, single submitter clinical testing The p.D217N variant (also known as c.649G>A), located in coding exon 3 of the CASR gene, results from a G to A substitution at nucleotide position 649. The aspartic acid at codon 217 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
