A Compound Heterozygous Mutation in the Ciliary Gene Causes Nephronophthisis Type 12.

Nephronophthisis (NPHP) is one of the renal ciliopathies and is also a cystic renal disorder with an autosomal recessive inheritance, which usually progresses to end-stage renal disease (ESRD). It affects children, adolescents, and young adults. In approximately 15% of cases, the features of a ciliopathy syndrome, which include liver fibrosis, skeletal anomalies, retinal abnormalities, and neurodevelopmental delay, will be present.
