Variant summary
Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM2BP4_ModerateBP6_Very_StrongBP7
The NM_000179.3(MSH6):c.2319C>A(p.Leu773Leu) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,876 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 (★★★). Synonymous variant affecting the same amino acid position (i.e. L773L) has been classified as Likely benign.

Submissions by phenotype
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 Benign:2
- -
Multifactorial likelihood analysis posterior probability 0.001-0.049 -
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. -
