GeneDx RCV000121564 SCV000515732 likely benign not specified 2017-10-16 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.

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 0.00027 in 251372 control chromosomes, predominantly at a frequency of 0.0038 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 7-fold the estimated maximal expected allele frequency for a pathogenic variant in MSH2 causing Lynch Syndrome phenotype (0.00057), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. c.2425G>A has been reported in the literature in individuals affected with Lynch Syndrome (Jiang_2019, Liu_2014, Pinard_2016, Tang_2009, Toh_2018, Xie_2018), predominantly in individuals of Asian origin. A database cites the variant to co-occur with a pathogenic variant in MSH2 (c.942+3A>T) and indicated that the variant did not cosegregate with disease in a family. Four ClinVar submissions (evaluation after 2014) cite the variant three times as likely benign and once as benign. Based on the evidence outlined above, the variant was classified as benign.
