Summaries for Hemolytic Uremic Syndrome, Atypical 2

UniProtKB/Swiss-Prot : 76 Hemolytic uremic syndrome atypical 2: An atypical form of hemolytic uremic syndrome. It is a complex genetic disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal failure and absence of episodes of enterocolitis and diarrhea. In contrast to typical hemolytic uremic syndrome, atypical forms have a poorer prognosis, with higher death rates and frequent progression to end-stage renal disease.

MalaCards based summary : Hemolytic Uremic Syndrome, Atypical 2, is also known as hemolytic uremic syndrome, atypical, susceptibility to, 2. An important gene associated with Hemolytic Uremic Syndrome, Atypical 2 is CD46 (CD46 Molecule). Affiliated tissues include kidney, and related phenotypes are hypertension and proteinuria
