Summaries for Methylmalonic Aciduria, Cbla Type

OMIM : 57 Methylmalonic aciduria is a genetically heterogeneous disorder of methylmalonate and cobalamin (cbl; vitamin B12) metabolism. Different forms of isolated methylmalonic aciduria have been classified according to complementation groups of cells in vitro. Patients with defects in the synthesis of AdoCbl are usually responsive to vitamin B12 therapy and are classified as 'cbl' type: these include cblA and cblB (251110), which is caused by mutation in the MMAB gene (607568) on 12q24. See also cblH (277410), which may be a subset of cblA. The 'mut' form of MMA (251000) is caused by mutation in the MUT gene on chromosome 6p. In general, the mut form of MMA is unresponsive to vitamin B12 therapy. Combined methylmalonic aciduria and homocystinuria may be seen in complementation groups cblC (277400), cblD (277410), cblF (277380), and cblJ (614857). (251100)

MalaCards based summary : Methylmalonic Aciduria, Cbla Type, also known as methylmalonic aciduria cbla type, is related to methylmalonic aciduria, cblb type and methylmalonic aciduria due to methylmalonyl-coa mutase deficiency, and has symptoms including seizures, tremor and vomiting. An important gene associated with Methylmalonic Aciduria, Cbla Type is MMAA (Metabolism Of Cobalamin Associated A). Related phenotypes are seizures and muscular hypotonia

Disease Ontology : 12 A methylmalonic acidemia characterized by autosomal recessive inheritance, defects in the synthesis of AdoCbl, vitamin B12 therapy responsiveness and that has material basis in homozygous or compound heterozygous mutation in the MMAA gene on chromosome 4q31.

UniProtKB/Swiss-Prot : 75 Methylmalonic aciduria type cblA: A disorder of methylmalonate and cobalamin metabolism due to defective synthesis of adenosylcobalamin.
