GeneDx	RCV000121562	SCV000170345	benign	not specified	2014-05-05	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.

Integrated Genetics/Laboratory Corporation of America	RCV000587872	SCV000696228	benign	not provided	2016-09-06	criteria provided, single submitter	clinical testing	Variant summary: The MSH2 c.1886A>G (p.Gln629Arg) variant involves the alteration of a non-conserved nucleotide. 3/3 in silico tools predict a benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 159/123118 control chromosomes, predominantly observed in the East Asian subpopulation at a frequency of 0.0174486 (151/8654). This frequency is about 31 times the estimated maximal expected allele frequency of a pathogenic MSH2 variant (0.0005683), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. This variant has also been reported in colorectal patients or HNPCC-related cancer without strong evidence for pathogenicity. In a family, while affected proband carried the variant, another affected cousin did not carry the variant, possibly suggesting that it did not co-segregate with disease in the family (Woo_2014). Multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as Benign.
