CEP41

Chr 7AR

centrosomal protein 41

Also known as: JBTS15, TSGA14

The protein is required for ciliogenesis and facilitates tubulin glutamylation in cilia by participating in the transport of TTLL6 tubulin polyglutamylase between the basal body and cilium. Mutations cause Joubert syndrome 15, an autosomal recessive ciliopathy characterized by neurological abnormalities. This gene shows high constraint against loss-of-function variants, indicating its critical role in normal development.

The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
