GeneDx	RCV000182549	SCV000234897	benign	not specified	2016-07-29	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.

Ambry Genetics	RCV000770694	SCV000317903	benign	Familial thoracic aortic aneurysm and aortic dissection	2017-04-28	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: 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.

Illumina Laboratory Services, Illumina	RCV000204065	SCV001278179	likely benign	Aortic aneurysm, familial thoracic 4	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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000182549	SCV001554564	benign	not specified	2021-03-25	criteria provided, single submitter	clinical testing	Variant summary: MYH11 c.935A>G (p.Asn312Ser) results in a conservative amino acid change located in the Myosin head, motor domain (IPR001609) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00068 in 251434 control chromosomes, predominantly at a frequency of 0.0083 within the East Asian subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 664 fold of the estimated maximal expected allele frequency for a pathogenic variant in MYH11 causing Thoracic Aortic Aneurysms And Dissections phenotype (1.3e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. Nine ClinVar submitters (evaluation after 2014) cite the variant as benign/likely benign and one ClinVar submitter (evaluation after 2014) cites it as uncertain significance. Based on the evidence outlined above, the variant was classified as benign.
