Autosomal recessive polycystic kidney disease (ARPKD) is the recessive form of polycystic kidney disease. It is associated with a group of congenital fibrocystic syndromes. [ 5 ] Mutations in the PKHD1 (chromosomal locus 6p12.2) cause ARPKD.
Pyruvate kinase deficiency is an inherited metabolic disorder of the enzyme pyruvate kinase which affects the survival of red blood cells. [ 4 ] [ 5 ] Both autosomal dominant and recessive inheritance have been observed with the disorder; classically, and more commonly, the inheritance is autosomal recessive .
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]
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.
Polycystic kidney disease (ADPKD) is a life threatening hereditary disorder; it is characterized by the development of fluid-filled cyst formation and expansion of the kidney and other organs. [3] It is an autosomal dominant disease, and it is the most common hereditary disorders with a rate of occurrence of approximately 1 in 1000. [4]
D-Bifunctional protein deficiency is an autosomal recessive peroxisomal fatty acid oxidation disorder. Peroxisomal disorders are usually caused by a combination of peroxisomal assembly defects or by deficiencies of specific peroxisomal enzymes. The peroxisome is an organelle in the cell similar to the lysosome that functions to detoxify the cell.
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 ...
Polycystin-1 is a large cell-surface glycoprotein involved in adhesive protein–protein and protein–carbohydrate interactions; however it is not clear if the PKD domain mediates any of these interactions. PKD domains are also found in other proteins, usually in the extracellular parts of proteins involved in interactions with other proteins.
