RCV000656816 | SCV000329190 | uncertain significance | not provided | 2023-11-01 | criteria provided, single submitter | clinical testing | Reported previously in an individual with malignant hyperthermia susceptibility (PMID: 25735680); Reported previously in an individual with Takotsubo cardiomyopathy that underwent whole exome sequencing; however, CACNA1S was only reported as a candidate gene and other potentially pathogenic variants were also reported in this individual (PMID: 25132214); Reported previously as a variant of uncertain significance in a patient with recurrent exertional rhabdomyolysis and possible malignant hyperthermia susceptibility; this patient also had a pathogenic variant in a different gene related to a separate diagnosis (PMID: 30094188); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 32054689, 25132214, 25735680, 30094188) |

RCV000277233 | SCV000353115 | benign | Hypokalemic periodic paralysis, type 1 | 2018-01-12 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |

Ambry Genetics | RCV002519032 | SCV003651888 | uncertain significance | Inborn genetic diseases | 2022-09-03 | criteria provided, single submitter | clinical testing | The c.1493G>T (p.R498L) alteration is located in exon 11 (coding exon 11) of the CACNA1S gene. This alteration results from a G to T substitution at nucleotide position 1493, causing the arginine (R) at amino acid position 498 to be replaced by a leucine (L). Based on data from gnomAD, the T allele has an overall frequency of 0.06% (168/282898) total alleles studied. The highest observed frequency was 0.1% (127/129198) of European (non-Finnish) alleles. This alteration was reported to be heterozygous in an individual with malignant hyperthermia susceptibility with positive in vitro contracture tests (Gillies, 2015). This amino acid position is highly conserved in available vertebrate species. The p.R498L alteration is predicted to be deleterious by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
