Labcorp Genetics (formerly Invitae), Labcorp RCV002020917 SCV002298225 likely pathogenic Familial adenomatous polyposis 2 2021-05-02 criteria provided, single submitter clinical testing This variant results in a copy number gain of the genomic region encompassing exon(s) 2 of the MUTYH gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be out-of-frame, and may result in an absent or disrupted protein product. Loss-of-function variants in MUTYH are known to be pathogenic (PMID: 18534194, 20663686). This variant has not been reported in the literature in individuals with MUTYH-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
