The treatment options for autosomal recessive polycystic kidney disease, given there is no current cure, are: [4] Medications for hypertension; Medications and/or surgery for pain; Antibiotics for infection; Dialysis (if kidney failure is present) Kidney transplantation(in serious cases)
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. [5] 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.
PKD is caused by abnormal genes which produce a specific abnormal protein which has an adverse effect on tubule development. PKD is a general term for two types, each having their own pathology and genetic cause: autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD). [10] [11]
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common, life-threatening inherited human disorders and the most common hereditary kidney disease. [ 1 ] [ 2 ] It is associated with large interfamilial and intrafamilial variability, which can be explained to a large extent by its genetic heterogeneity and modifier genes ...
Human polycystin 1 is a huge protein of 4303 amino acyl residues (aas). Its repeated leucine-rich (LRR) segment is found in many proteins. According to the UniProt description, polycystin 1 contains 16 polycystic kidney disease (PKD) domains, one LDL-receptor class A domain, one C-type lectin family domain, and 16-18 putative TMSs in positions between residues 2200 and 4100.

Polycystin 1 (PC1) is a protein that in humans is encoded by the PKD1 gene. [5] [6] Mutations of PKD1 are associated with most cases of autosomal dominant polycystic kidney disease, a severe hereditary disorder of the kidneys characterised by the development of renal cysts and severe kidney dysfunction. [7]
PKD domains are also found in other proteins, usually in the extracellular parts of proteins involved in interactions with other proteins. For example, domains with a PKD-type fold are found in archaeal S-layer proteins that protect the cell from extreme environments, and in the human receptor SorCS2. Human proteins containing this domain
Polycystin-2 (PC2) [5] is a protein that in humans is encoded by the PKD2 gene. [6] [7] [8] The gene PKD2 also known as TRPP2, encodes a member of the polycystin protein family, called TRPP, and contains multiple transmembrane domains, and cytoplasmic N- and C-termini. The protein may be an integral membrane protein involved in cell-cell/matrix ...
