Diseases

Show/Hide Table
Disease IDSourceNameDescription
300868 OMIMMultiple congenital anomalies-hypotonia-seizures syndrome 2 (MCAHS2)An X-linked recessive developmental disorder characterized by dysmorphic features, neonatal hypotonia, myoclonic seizures, and variable congenital anomalies involving the central nervous, cardiac, and urinary systems. Most affected individuals die in infancy. The disease is caused by variants affecting the gene represented in this entry.
300818 OMIMParoxysmal nocturnal hemoglobinuria 1 (PNH1)A disorder characterized by hemolytic anemia with hemoglobinuria, thromboses in large vessels, and a deficiency in hematopoiesis. Red blood cell breakdown with release of hemoglobin into the urine is manifested most prominently by dark-colored urine in the morning. Disease susceptibility is associated with variants affecting the gene represented in this entry.
