Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000035342	SCV000058990	benign	not specified	2012-05-07	criteria provided, single submitter	clinical testing	1590+14T>C in Intron 12 of KCNQ1: This variant is not expected to have clinical significance because it is not located within the conserved splice consensus seq uence and has been identified in 11.5% (806/7020) of European American chromosom es from a broad population by the NHLBI Exome Sequencing Project (http://evs.gs. washington.edu/EVS; dbSNP rs11024034).
GeneDx	RCV000035342	SCV000169944	benign	not specified	2012-06-14	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.

Illumina Laboratory Services, Illumina	RCV000283709	SCV000370356	benign	Short QT syndrome type 2	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 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.
