VITAMIN B12-RESPONSIVE METHYLMALONIC ACIDEMIA TYPE CBLB
Alternate names
VITAMIN B12-RESPONSIVE METHYLMALONIC ACIDEMIA TYPE CBLB Is also known as vitamin b12-responsive methylmalonic aciduria, type cblb, methylmalonic acidemia, cblb type, methylmalonic aciduria, vitamin b12-responsive, due to defect in synthesis of adenosylcobalamin, cblb type
Description
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 cblB and cblA (OMIM ). The cblA type is caused by mutation in the MMAA gene (OMIM ). The 'mut' type (OMIM ) is caused by mutation in the MUT gene; 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 (OMIM ), cblD (OMIM ), and cblF (OMIM ).
Most common symptoms of VITAMIN B12-RESPONSIVE METHYLMALONIC ACIDEMIA TYPE CBLB
- Intellectual disability
- Seizures
- Global developmental delay
- Generalized hypotonia
- Ataxia
