RCV000198593 | SCV000253863 | pathogenic | Familial adenomatous polyposis 2 | 2022-05-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 216081). This variant has not been reported in the literature in individuals affected with MUTYH-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Lys492*) 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). |

RCV001184572 | SCV001350593 | pathogenic | Hereditary cancer-predisposing syndrome | 2020-01-15 | criteria provided, single submitter | clinical testing | This variant is located in the MUTYH protein. Splice site prediction tools suggest that this variant may not impact RNA splicing. This variant has not been identified 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 | RCV001184572 | SCV002697041 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2024-11-12 | criteria provided, single submitter | clinical testing | The c.1474A>T variant (also known as p.K492*), located in coding exon 14 of the MUTYH gene, results from an A to T substitution at nucleotide position 1474. This changes the amino acid from a lysine to a stop codon within coding exon 14. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the majority of available evidence to date, this variant is likely to be pathogenic. |
