KIF24

Chr 9

kinesin family member 24

Also known as: C9orf48, bA571F15.4

The protein is a microtubule-dependent motor protein that acts as a negative regulator of ciliogenesis by controlling microtubule polymerization at the mother centriole and mediating recruitment of centriolar proteins. Mutations cause autosomal recessive neurodevelopmental disorder with spastic paraplegia, microcephaly, and seizures, reflecting the critical role of proper cilia regulation in brain development. The gene shows minimal constraint against loss-of-function variants, consistent with recessive inheritance patterns.

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.
