Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000039892	SCV000063583	likely benign	not specified	2021-01-26	criteria provided, single submitter	clinical testing	13451-7C>T in intron 55 of TTN: This variant is not expected to have clinical significance because a C>T change at this position does not diverge from the splice consensus sequence and does not impact splicing. Additionally, it has been identified in 0.9% (215/25030) South Asian and 0.02% (17/104638) European chromosomes by gnomAD (https://gnomad.broadinstitute.org/). ACMG/AMP criteria applied: BS1, BS4.

Illumina Laboratory Services, Illumina	RCV000272411	SCV000424563	likely benign	Dilated cardiomyopathy 1G	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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Illumina Laboratory Services, Illumina	RCV000342528	SCV000424567	uncertain significance	Autosomal recessive limb-girdle muscular dystrophy type 2J	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, 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.
GeneDx	RCV000039892	SCV000515096	benign	not specified	2015-03-27	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.
