Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002469952 SCV002765956 likely pathogenic Hereditary nonpolyposis colon cancer 2022-11-04 criteria provided, single submitter clinical testing Variant summary: MSH6 c.3802-1G>T is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: Two predict the variant abolishes a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 251016 control chromosomes. To our knowledge, no occurrence of c.3802-1G>T in individuals affected with Lynch Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
