Labcorp Genetics (formerly Invitae), Labcorp RCV002796919 SCV003196595 likely pathogenic Multiple endocrine neoplasia, type 1 2022-05-25 criteria provided, single submitter clinical testing 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. This variant disrupts the NLS2 domain of the MEN1 protein, which is important for DNA binding and repression of cell proliferation (PMID: 15331604, 16449969). While functional studies have not been performed to directly test the effect of this variant on MEN1 protein function, this suggests that disruption of this region of the protein is causative of disease. This premature translational stop signal has been observed in individual(s) with MEN1-related conditions (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu491*) in the MEN1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 120 amino acid(s) of the MEN1 protein.
