Fructose-1,6-bisphosphate aldolase A (fructose-bisphosphate aldolase; EC 4.1.2.13) deficiency is an autosomal recessive disorder associated with hereditary hemolytic anemia. To clarify the molecular mechanism of the deficiency at the nucleotide level, we have cloned aldolase A cDNA from a patient's poly(A)+ RNA that was expressed in cultured lymphoblastoid cells. Nucleotide analysis of the pati...
BACKGROUND Homozygotes for the thermolabile mutation (TT genotype) of the methylenetetrahydrofolate reductase (MTHFR; EC 1.5.1.20) enzyme have elevated plasma concentrations of the cardiovascular disease risk factor homocysteine, particularly if folate depleted. OBJECTIVE We examined the relations between thermolabile MTHFR, plasma homocysteine, plasma folate, and vascular disease risk. DES...
BACKGROUND Hypermocysteinemia has been substantiated as a risk factor for occlusive vascular disease. A common mutation (nucleotide 677 C-->T) has been described recently in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, which results in a valine for alanine substitution, a thermolabile enzyme, and a tendency to elevate plasma homocysteine levels and which has been proposed to contr...
