Labcorp Genetics (formerly Invitae), Labcorp RCV003615035 SCV004477119 uncertain significance Colorectal cancer, hereditary nonpolyposis, type 7 2023-05-05 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu864Phefs*4) in the MLH3 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in MLH3 cause disease. This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with MLH3-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
