Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_000179.3(MSH6):c.2708C>A(p.Pro903His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P903L) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Oct 05, 2016 | This variant is denoted MSH6 c.2708C>A at the cDNA level, p.Pro903His (P903H) at the protein level, and results in the change of a Proline to a Histidine (CCT>CAT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. MSH6 Pro903His was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Proline and Histidine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. MSH6 Pro903His occurs at a position that is conserved across species and is located in the MutS domain (Terui 2013). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether MSH6 Pro903His is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. - |
