Any renal-hepatic-pancreatic dysplasia in which the cause of the disease is a mutation in the NPHP3 gene.
Features include always present findings: Stage 5 chronic kidney disease, Reduced kidney function (renal insufficiency), Liver scarring (cirrhosis) (cirrhosis), and Hyperechogenic pancreas; and common findings: Preauricular pit, Situs inversus totalis, Enlarged liver (hepatomegaly), and Portal hypertension and others. 31 total HPO annotations.

NPHP3 encodes nephrocystin 3 (1,330 aa). Required for normal ciliary development and function. Highest expression in Ovary (63.6 TPM) and Fallopian Tube (51.7 TPM).
Renal-hepatic-pancreatic dysplasia 1 is associated with mutations in the NPHP3 gene on chromosome 3.
The NPHP3 protein participates in Myristoylated NPHP3 translocates into the ciliary membrane, UNC119B stimulates translocation of myristoylated ciliary cargo to the primary cilium, and RP2:ARL3:GDP:UNC119B dissociates pathways.
NPHP3 is classified as a druggable target with score 0.0.
Genetic testing for NPHP3 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 4 always present features, 9 common features.
