<prompt> Gene NPHP1 encodes?FibrocystinNephrocystinPolycystinPodocin  <response>: Ans. is b i.e., Nephrocystin Nephrocystin-1 is a protein that in humans is encoded by the NPHP1 gene on chromosome 2q. The protein is known to play a role in functioning of cilia. Mutations in this gene cause familial juvenile nephronophthisis, a medullary cystic kidney disease. It is a form of ciliopathy. Other genes of this family , NPHP 2,3,4 encode for proteins inversin, Nephrocystin-3 and Nephrocystin-4 respectivelyAbout other options PKHD1 Polycystic Kidney and Hepatic Disease 1 which codes for a protein fibrocystin PKD adult polycystic kidney gene on chromosome 16 encoding for polycystin. NPHS-2 gene lq25-31 enodes for Podocin Slit diaphragm Steroid resistant nephrotic syndrome.
