Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000601988 SCV000917653 uncertain significance not specified 2017-12-26 criteria provided, single submitter clinical testing Variant summary:The MLH1 c.117-10G>A variant involves the alteration of a non-conserved intronic nucleotide. Mutation taster predicts a damaging outcome for this variant. 3/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 15/246218 control chromosomes (gnomAD), only observed in the East Asian subpopulation at a frequency of 0.00087 (15/17248). This frequency is about 1.2 times the estimated maximal expected allele frequency of a pathogenic MLH1 variant (0.0007105), suggesting this is possibly a benign polymorphism found primarily in the populations of East Asian origin. This variant has been reported in one Lynch Syndrome family without strong evidence for or against pathogenicity and classified as variant of unknown significance (Liu_2014). In addition, one clinical diagnostic laboratory has classified this variant as likely benign. Taken together, this variant is classified as variant of unknown significance-possibly benign.
