Variant summary
Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_ModerateBP6_Very_Strong
The NM_000179.3(MSH6):c.364G>A(p.Glu122Lys) variant causes a missense change. The variant allele was found at a frequency of 0.0000266 in 1,614,106 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E122G) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Benign:3
- -
- -
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 Uncertain:1Benign:1
This variant is considered benign. This variant has been observed in conjunction with multiple pathogenic variants, reducing the likelihood this variant itself is pathogenic. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 27363726]. -

Variant summary: MSH6 c.364G>A (p.Glu122Lys) results in a conservative amino acid change located in the PWWP domain of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 9.5e-05 in 251490 control chromosomes, predominantly at a frequency of 0.00055 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 4 fold of the estimated maximal expected allele frequency for a pathogenic variant in MSH6 causing Hereditary Nonpolyposis Colorectal Cancer phenotype (0.00014), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.364G>A has been reported in the literature. These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Nonpolyposis Colorectal Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 23621914, 25419514). ClinVar contains an entry for this variant (Variation ID: 182662). Based on the evidence outlined above, the variant was classified as likely benign. -
