Labcorp Genetics (formerly Invitae), Labcorp RCV005119518 SCV005746602 likely pathogenic Multiple endocrine neoplasia, type 1 2024-03-16 criteria provided, single submitter clinical testing This sequence change falls in intron 7 of the MEN1 gene. It does not directly change the encoded amino acid sequence of the MEN1 protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with clinical features of MEN1-related conditions (Invitae). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that this variant results in activation of a cryptic slice site and introduces a premature termination codon (Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. 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.
