PIMREG

Chr 17

PICALM interacting mitotic regulator

Also known as: CATS, FAM64A, RCS1

The PIMREG protein is involved in controlling the metaphase-to-anaphase transition during mitosis and localizes to the nucleolus and nucleoplasm. Mutations cause neurodevelopmental disorders with intellectual disability, though the gene shows relatively low constraint to loss-of-function variation. The inheritance pattern and additional clinical details require further characterization.

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
