ADGB and ciliopathy: Those genes, mostly reported in case reports or small cohorts of patients, are ARL2BP—which codifies for a ciliary protein and might be involved in the development of syndromic ciliopathy [124], CTE1/DRC5, encoding a component of a multiprotein complex which regulates the beating of cilia and flagellum and whose mutation is associated with reduced sperm motility [125], ADGB, causing reduced sperm motility by the binding of ADGB to calmodulin [126], and DNALI1, whose mutation causes isolated asthenoozospermia due to injury to inner dynein arms [110].
