GeneDx RCV000413560 SCV000490452 pathogenic not provided 2016-05-04 criteria provided, single submitter clinical testing The R25X nonsense variant in the CASR gene has been reported previously in patients with primary hyperparathyroidism and familial hypocacliuric hypercalcemia (Frank-Raue et al, 2011; Ward et al., 2006). This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. In addition, the R25X variant was not observed at any significant frequency in approximately 6,500 individuals of European and African American ancestry by the NHLBI Exome Sequencing Project. In summary, we interpret R25X as a pathogenic variant.
Invitae RCV000457695 SCV000550973 pathogenic Hypocalciuric hypercalcemia, familial, type 1; Hypocalcemia, autosomal dominant 1 2017-07-11 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal at codon 25 (p.Arg25*) of the CASR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CASR are known to be pathogenic. This particular variant has been reported in two individuals  affected with familial hypocalciuric hypercalcaemia (FHH) in a single family (PMID: 16649980) and an individual affected with primary hyperparathyroidism (HPT) (PMID: 21521328). For these reasons, this variant has been classified as Pathogenic.
