RCV000485027 | SCV000571325 | likely pathogenic | not provided | 2016-08-15 | criteria provided, single submitter | clinical testing | This deletion of one nucleotide in MUTYH is denoted c.1321delG at the cDNA level and p.Glu441ArgfsX11 (E441RfsX11) at the protein level. The normal sequence, with the base that is deleted in braces, is TGGG[G]AGGT. The deletion causes a frameshift which changes a Glutamic Acid to an Arginine at codon 441, and creates a premature stop codon at position 11 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Based on the currently available information, we consider this deletion to be a likely pathogenic variant. |

RCV000693940 | SCV000822363 | pathogenic | Familial adenomatous polyposis 2 | 2021-11-17 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Glu441Argfs*11) 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 not present in population databases (gnomAD no frequency). 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: 421975). For these reasons, this variant has been classified as Pathogenic. |

RCV000693940 | SCV005429808 | pathogenic | Familial adenomatous polyposis 2 | 2024-05-07 | criteria provided, single submitter | clinical testing | This variant deletes 1 nucleotide in exon 13 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 not been reported in individuals affected with hereditary cancer in the literature. 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. |
