Diseases

Show/Hide Table
Disease IDSourceNameDescription
236270 OMIMHomocystinuria-megaloblastic anemia, cblE complementation type (HMAE)An autosomal recessive inborn error of metabolism resulting from defects in the cobalamin-dependent pathway that converts homocysteine to methionine. It causes delayed psychomotor development, megaloblastic anemia, homocystinuria, and hypomethioninemia. Cells from patients with HMAE fail to incorporate methyltetrahydrofolate into methionine in whole cells, but cell extracts show normal methionine synthase activity in the presence of a reducing agent. The disease is caused by variants affecting the gene represented in this entry.
601634 OMIMNeural tube defects, folate-sensitive (NTDFS)The most common NTDs are open spina bifida (myelomeningocele) and anencephaly. Disease susceptibility is associated with variants affecting the gene represented in this entry.
