The Lewis Polycystic Kidney (LPK) rat phenotype has been characterized and classified as a model of nephronophthisis (NPHP9, caused by mutation of the Nek8 gene) for which polycystic kidneys are one of the main pathologic features.
Mutations in NEK8 have been previously reported in three fetuses (from a single family) with renal-hepatic-pancreatic dysplasia 2 (RHPD2), similar to Ivemark syndrome, and in three individuals with nephronophthisis (NPHP9).
Missense mutations in NEK8/NPHP9 have been identified in juvenile cystic kidney jck mice and in patients suffering from nephronophthisis (NPH), an autosomal-recessive cystic kidney disease.
Missense mutations in NEK8/NPHP9 have been identified in juvenile cystic kidney jck mice and in patients suffering from nephronophthisis (NPH), an autosomal-recessive cystic kidney disease.
Mutations in the never-in-mitosis A-related kinase, Nek8, are associated with cystic kidney disease in both humans and mice, with Nek8 being the NPHP9 gene in the human juvenile cystic kidney disease, nephronophthisis.
We hypothesized that mutations in NEK8 might cause nephronophthisis in humans, so we performed mutational analysis in a worldwide cohort of 588 patients.
