Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000179.3(MSH6):c.1308C>A(p.Tyr436Ter) variant causes a stop gained change involving the alteration of a non-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. Y436Y) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
Lynch syndrome 5 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Aug 11, 2023 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 06, 2017 | The p.Y436* pathogenic mutation (also known as c.1308C>A), located in coding exon 4 of the MSH6 gene, results from a C to A substitution at nucleotide position 1308. This changes the amino acid from a tyrosine to a stop codon within coding exon 4. 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. - |
