Phenotypes associated with the disease atypical hemolytic-uremic syndrome with B factor anomaly (OMIM:612924):
- Acute kidney injury (HP:0001919): Sudden loss of renal function, as manifested by decreased urine production, and a rise in serum creatinine or blood urea nitrogen concentration (azotemia). Evidence: PCS. (PMID:17182750)
- Microangiopathic hemolytic anemia (HP:0001937). Evidence: TAS. (OMIM:612924)
- Hemolytic-uremic syndrome (HP:0005575): A thrombotic microangiopathy with presence of non-immune, intravascular hemolytic anemia, thrombocytopenia and acute kidney injury. A vicious cycle of complement activation, endothelial cell damage, platelet activation, and thrombosis is the hallmark of the disease. Evidence: PCS. Frequency: 9/12. (PMID:17182750)
- Anemia (HP:0001903): A reduction in erythrocytes volume or hemoglobin concentration. Evidence: TAS. (OMIM:612924)
- Hematuria (HP:0000790): The presence of blood in the urine. Hematuria may be gross hematuria (visible to the naked eye) or microscopic hematuria (detected by dipstick or microscopic examination of the urine). Evidence: TAS. (OMIM:612924)
- Hypertension (HP:0000822): The presence of chronic increased pressure in the systemic arterial system. Evidence: TAS. Frequency: Frequent (HP:0040282). (OMIM:612924)
- Proteinuria (HP:0000093): Increased levels of protein in the urine. Evidence: TAS. (OMIM:612924)
- Anuria (HP:0100519): Absence of urine, clinically classified as below 50ml/day. Evidence: TAS. (OMIM:612924)
- Thrombocytopenia (HP:0001873): A reduction in the number of circulating thrombocytes. Evidence: TAS. (OMIM:612924)
- Increased blood urea nitrogen (HP:0003138): An increased amount of nitrogen in the form of urea in the blood. Evidence: TAS. (OMIM:612924)
- Elevated circulating creatinine concentration (HP:0003259): An increased amount of creatinine in the blood. Evidence: TAS. (OMIM:612924)
- Autosomal dominant inheritance (HP:0000006): A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele. Evidence: PCS. (PMID:17182750)
