PKHD1
Fibrocystin is a large, receptor-like protein that is thought to be involved in the tubulogenesis and/or maintenance of duct-lumen architecture of epithelium. FPC associates with the primary cilia of epithelial cells and co-localizes with the Pkd2 gene product polycystin-2 (PC2), suggesting that these two proteins may function in a common molecular pathway. Pathology Mutations of its encoding gene (chromosomal locus 6p12.2) can cause autosomal recessive polycystic kidney disease Autosomal recessive polycystic kidney disease (ARPKD) is the recessive form of polycystic kidney disease. It is associated with a group of congenital fibrocystic syndromes. Mutations in the ''PKHD1'' (chromosomal locus 6p12.2) cause ARPKD. Signs .... PKHD1 gene codes for fibrocystin. Fibrocystin is found in the epithelial cell of both the renal tubule and the bile ducts. A mutation in PKHD1 (can be autosomal recessive pattern or spontaneous mutations) leading to a deficiency in fibrocystin causes chara ...

Autosomal Recessive Polycystic Kidney Disease
Autosomal recessive polycystic kidney disease (ARPKD) is the recessive form of polycystic kidney disease. It is associated with a group of congenital fibrocystic syndromes. Mutations in the ''PKHD1'' (chromosomal locus 6p12.2) cause ARPKD. Signs and symptoms Symptoms and signs include abdominal discomfort, polyuria, polydipsia, incidental discovery of hypertension, and abdominal mass. The classic presentation for ARPKD is systemic hypertension with progression to end-stage kidney disease (ESKD) by the age of 15. In a typical presentation, a small number of individuals with ARPKD live to adulthood with some kidney function; but with significant deterioration in liver function. This outcome is postulated to result from expression of the polycystic kidney and hepatic disease gene PKHD1, which is located on chromosome 6p. In severe cases, a fetus will present with oligohydramnios and as a result, may present with Potter sequence.Shastry SM, Kolte SS, Sanagapati PR. Potter's Sequenc ...
