Submissions by phenotype
Hereditary cancer-predisposing syndrome Benign:2
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
- -
Lynch syndrome 5 Benign:1
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
not specified Benign:1
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

The MSH6 p.Arg411= variant was not identified in the literature nor was it identified in the MutDB, LOVD 3.0, UMD-LSDB, Zhejiang Colon Cancer Database, Mismatch Repair Genes Variant Database, or Insight Hereditary Tumors Database. The variant was identified in dbSNP (ID: rs554843104), ClinVar (classified likely benign by Ambry Genetics, Color Genomics Inc and GeneDx), Clinvitae (1x), Cosmic (1x in a malignant melanoma), and in control databases in 5 of 246106 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). It was observed in the South Asian population in 5 of 30782 chromosomes (freq: 0.0002) but not in the African, Other, Latino, European Non-Finnish, Ashkenazi Jewish, East Asian and Finnish populations. The p.Arg411= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
