Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000251.3(MSH2):c.1111G>T(p.Glu371Ter) variant causes a stop gained 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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. E371E) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Hereditary nonpolyposis colorectal neoplasms Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 16, 2023 | This sequence change creates a premature translational stop signal (p.Glu371*) in the MSH2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MSH2-related conditions. ClinVar contains an entry for this variant (Variation ID: 566113). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 05, 2019 | The p.E371* pathogenic mutation (also known as c.1111G>T), located in coding exon 7 of the MSH2 gene, results from a G to T substitution at nucleotide position 1111. This changes the amino acid from a glutamic acid to a stop codon within coding exon 7. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
