KIF15

Chr 3AR

kinesin family member 15

Also known as: BRDCS2, HKLP2, KLP2, KNSL7, NY-BR-62

KIF15 encodes a plus-end directed kinesin motor protein that hydrolyzes ATP to drive microtubule-based movement and is essential for mitotic spindle assembly and centrosome separation. Biallelic mutations cause Braddock-Carey syndrome 2, an autosomal recessive disorder. The gene shows tolerance to loss-of-function variants in the general population (pLI near zero), which is consistent with the recessive inheritance pattern observed in affected patients.

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.

GOFprediction above median

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.
