However, we found no renal cysts in mice with collecting duct excision of Vangl2. Furthermore, there is no evidence that PCP-dependent OCD is disturbed prior to cyst appearance in mouse mutants with excision of Pkd1 or Pkd2 in renal tubules (genes mutated in autosomal dominant polycystic kidney disease) [42]. The gene discussed is VANGL2; the disease is Renal cyst.
