It has been identified in 45.8% (2016/4406) of African American chromosomes from a broad population by the NHLBI Exome Sequ encing Project (http://evs.gs.washington.edu/EVS; dbSNP rs2229144).

Illumina Laboratory Services, Illumina	RCV000271603	SCV000412529	benign	Malignant hyperthermia, susceptibility to, 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.

GeneDx	RCV000079174	SCV000519601	benign	not specified	2016-01-25	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Variant was observed in a homozygous state in population databases more than expected for disease. 9 reputable source/s reports the variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation. A synonymous variant not located in a splice region.
