RCV000773209 | SCV000906796 | pathogenic | Hereditary cancer-predisposing syndrome | 2020-03-21 | criteria provided, single submitter | clinical testing | This variant changes 1 nucleotide in exon 2 of the MUTYH gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been identified in 1/251484 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of MUTYH function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. |
Ambry Genetics | RCV000773209 | SCV001179261 | pathogenic | Hereditary cancer-predisposing syndrome | 2023-10-24 | criteria provided, single submitter | clinical testing | The p.Q29* pathogenic mutation (also known as c.85C>T), located in coding exon 2 of the MUTYH gene, results from a C to T substitution at nucleotide position 85. This changes the amino acid from a glutamine to a stop codon within coding exon 2. 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. |

RCV000671051 | SCV001406787 | pathogenic | Familial adenomatous polyposis 2 | 2023-09-27 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Gln29*) in the MUTYH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MUTYH are known to be pathogenic (PMID: 18534194, 20663686). This variant is present in population databases (rs768386527, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with MUTYH-related conditions. ClinVar contains an entry for this variant (Variation ID: 555262). RNA analysis performed to evaluate the impact of this premature translational stop signal on mRNA splicing indicates it does not significantly alter splicing (Invitae). For these reasons, this variant has been classified as Pathogenic. |
