GeneDx	RCV000036747	SCV000234999	benign	not specified	2014-05-06	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.

However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0053 in 244908 control chromosomes in the gnomAD database, including 27 homozygotes. The observed variant frequency is approximately 89 fold of the estimated maximal expected allele frequency for a pathogenic variant in RYR2 causing Arrhythmia phenotype (6e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.4597-11delA in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Both laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign.

Ambry Genetics	RCV002336124	SCV002637554	benign	Cardiovascular phenotype	2014-12-08	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
