Description

The MLH1 c.-33T>G variant is located in the 5' untranslated region. This variant has been reported as a variant of uncertain significance in a patient with Lynch syndrome in a screen for causal MLH1 promoter and cis regulatory elements (Morak et al. 2018. PubMed ID: 29472279). This variant is reported in 0.010% of alleles in individuals of East Asian descent in gnomAD, which may be too common to be a primary cause of disease. In ClinVar, it is interpreted as uncertain and likely benign (https://www.ncbi.nlm.nih.gov/clinvar/variation/234367/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
