Summaries for Nephronophthisis 20

OMIM : 58 Nephronophthisis-20 is an autosomal recessive tubulointerstitial nephritis characterized by progressive renal fibrosis resulting in end-stage renal failure. The age at onset is relatively late compared to other forms of NPHP, and patients develop end-stage renal disease in the second or third decades. Unlike most other forms of NPHP, NPHP20 does not have features of a ciliopathy and patients do not appear to have extrarenal manifestations (summary by Macia et al., 2017). For a general phenotypic description and a discussion of genetic heterogeneity of nephronophthisis, see NPHP1 (256100). (617271)

MalaCards based summary : Nephronophthisis 20, is also known as nphp20. An important gene associated with Nephronophthisis 20 is MAPKBP1 (Mitogen-Activated Protein Kinase Binding Protein 1). Affiliated tissues include kidney, and related phenotypes are nephronophthisis and renal cyst

Disease Ontology : 12 A nephronophthisis that has material basis in homozygous or compound heterozygous mutation in the MAPKBP1 gene on chromosome 15q15.

UniProtKB/Swiss-Prot : 76 Nephronophthisis 20: A form of nephronophthisis, an autosomal recessive chronic tubulo- interstitial nephritis that progresses to end-stage renal failure. Some patients have cystic kidneys of normal size and no extrarenal manifestations, whereas others have enlarged renal size and severe extrarenal defects, including hypertrophic obstructive cardiomyopathy, aortic stenosis, pulmonary stenosis, patent ductus arteriosus, situs inversus, and periportal liver fibrosis. NPHP20 patients do not show extrarenal manifestations or evidence of a ciliopathy, such as situs inversus or polydactyly.
