GeneDx RCV000212534 SCV000211141 benign not specified 2014-07-16 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.

ESE finder predicts that this variant may affect ESE binding sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 8/121400 control chromosomes at a frequency of 0.0000659, which does not exceed the estimated maximal expected allele frequency of a pathogenic MLH1 variant (0.0007105). A publication cites the variant in 2 pts diagnosed with ovarian cancer, however, limited information is provided (ie, no co-occurrence or cosegregation data). An internal LCA sample reports the variant to co-olccur with two MUTYH DVs, c.536A>G and c.1187G>A. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign/benign. Taken together, this variant is classified as "likely benign."
