Human Genome Sequencing Center Clinical Lab,Baylor College of Medicine RCV000709737 SCV000840003 pathogenic Lynch syndrome II 2017-05-24 criteria provided, single submitter clinical testing This c.116+1G>A variant in the MLH1 gene has been reported in one patient with colorectal cancer diagnosed before 30 years of age [PMID 9718327]. This variant has not been observed in our patient database nor has been detected in the ExAC database. This variant was however reported in ClinVar and was classified as likely pathogenic in 2013 by an expert panel (SCV000106118.2). This variant affects the invariant donor splice site of intron 1 of the MLH1 gene. While not validated for clinical use, computer-based algorithms predict this c.116+1G>A change to disrupt the splice site. This variant is thus classified as pathogenic.
