Illumina Laboratory Services, Illumina	RCV000370345	SCV000436776	likely benign	Collagen 6-related myopathy	2017-04-28	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
Illumina Laboratory Services, Illumina	RCV000259316	SCV000436777	likely benign	Myosclerosis	2017-04-28	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard	RCV000990372	SCV001435223	benign	Bethlem myopathy 1A		criteria provided, single submitter	research	The heterozygous p.Arg853Gln variant in COL6A2 has been identified in 2 individuals, 1 with Bethlem myopathy and 1 with trisomy 21 and atrioventricular septal defect (PMID: 15689448, 23040494), but has also been identified in >1% of South Asian chromosomes and 4 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, this variant meets criteria to be classified as benign for Bethlem myopathy.
