Color Diagnostics, LLC DBA Color Health RCV001186630 SCV001353108 uncertain significance Hereditary cancer-predisposing syndrome 2019-12-12 criteria provided, single submitter clinical testing This missense variant replaces tyrosine with phenylalanine at codon 283 of the MLH1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
