Variant summary
Our verdict is Benign. The variant received -11 ACMG points: 2P and 13B. PM2BP4_StrongBP6_Very_StrongBP7
The NM_000179.3(MSH6):c.3456A>G(p.Val1152Val) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,461,732 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★).

Variant summary: The MSH6 c.3456A>G (p.Val1152Val) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. Mutation taster predicts a damaging outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant does not affect binding of any ESE sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 1/121342 control chromosomes at a frequency of 0.0000082, which does not exceed the estimated maximal expected allele frequency of a pathogenic MSH6 variant (0.0001421). This variant has been reported in one patient with ovarian cancer who also carries MSH6 c.3083C>A (p.Ser1028X) (Chui_2014). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign. Taken together, this variant is classified as likely benign. -
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. -
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. -
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. -
