Abstract excerpt
In the cblF defect of vitamin B(12) (cobalamin) metabolism, cobalamin is trapped in lysosomes. Consequently, cobalamin coenzyme synthesis is blocked, and cofactors for methionine synthase and methylmalonyl-coenzyme A (CoA) mutase are deficient. We recently identified LMBRD1 as the causative gene located on chromosome 6q13 and showed that 18 out of 24 alleles in unrelated patients carried the deletion c.1056delG...
