TypeGene ModificationChromosome rearrangementProtein expressionProtein Function
constitutional       loss of function
in polycystic kidney disease by inhibition of renal ciliogenesis
constitutional   deletion    
in ciliopathy with hydrocephalus, isolated craniosynostosis, hypertelorism, and clefting
tumoral     --over  
in the majority of human prostate cancer cell lines and primary tumor biopsies
constitutional   deletion    
selective deletion of KIF3A in osteoblasts disrupts primary cilia formation and/or function and impairs osteoblast-mediated bone formation through multiple pathways including intracellular calcium, hedgehog and Wnt signaling
Susceptibility to atopic dermatitis (AD)
Variant & Polymorphism SNP
  • rs2897442 in KIF3A within the cytokine cluster at 5q31.1 associated with atopic dermatitis (AD)
  • Candidate gene
    Therapy target
  • mouse mutants lacking the KIF3A showed situs inversus and embryonic ciliary morphogenesis defects
  • mouse embryos lacking KIF3A die at 10 days postcoitum, exhibit randomized establishment of L-R asymmetry and display numerous structural abnormalities
  • complete loss of Kif3a led to large accumulations of opsin, arrestin and membranes within the photoreceptor inner segment and caused apoptotic photoreceptor cell death
  • Kif3a mutant zebrafish exhibited curved body axes and kidney cysts
