RPGRIP1L is a human gene.^[1]

Function

The protein encoded by this gene is localized to primary cilia and centrosomes in ciliated human epithelial kidney cells. RPGRIP1L colocalized at the basal body-centrosome complex with the proteins NPHP4, NPHP6, and TUBG1.^[2][3]

Clinical significance

Mutations in the RPGRIP1L gene are associated with Joubert syndrome and Meckel syndrome which belong to a group of developmental autosomal recessive disorders that are associated with cilium dysfunction.^[2] Mutations in this gene are also associated with nephronophthisis.^[4] Copy number variation affecting the gene was associated with schizophrenia in one study.^[5]
