Early Onset Methylmalonic Aciduria and Homocystinuria cblC Type With Demyelinating Neuropathy [PDF]
Methylmalonic aciduria and homocystinuria, cblC type, is the most common inborn error of vitamin B 12 (cobalamin) metabolism. The recent cloning of the disease gene, MMACHC, has permitted genotypephenotype correlation.

A 17 Year Old With Developmental Delay Presenting With Increasing Confusion and Imbalance
ABSTRACT Methylmalonic acidemia is an autosomal recessive genetic disorder primarily caused by defects in methylmalonyl‐CoA mutase and cobalamin (vitamin B12) metabolism. These defects disrupt the tricarboxylic acid cycle and oxidative phosphorylation, leading to the abnormal accumulation of metabolic products such as methylmalonic acid, propionic acid,

Proteinuria as a presenting sign of combined methylmalonic acidemia and homocysteinemia: case report
Background Disorders of the metabolism and absorption of vitamin B12 can lead to decrease in activity of methionine synthetase and methylmalonate coenzyme A mutase (MMUT), which results in increased levels of methylmalonic acid and homocysteine in blood ...
