Illumina Laboratory Services, Illumina	RCV000320906	SCV000356325	uncertain significance	Catecholaminergic polymorphic ventricular tachycardia 1	2018-01-13	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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Ambry Genetics	RCV002347815	SCV002653203	uncertain significance	Cardiovascular phenotype	2021-04-14	criteria provided, single submitter	clinical testing	The p.R1888Q variant (also known as c.5663G>A), located in coding exon 37 of the RYR2 gene, results from a G to A substitution at nucleotide position 5663. The arginine at codon 1888 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is not well 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.
