The biochemical features in these four subjects are distinguishable from subjects homozygous for the thermolabile MTHFR, whose specific activity is approximately 50% of the normal mean, and from heterozygotes for severe MTHFR deficiency, in whom the enzyme is thermostable and has a specific activity of about 50% of the normal mean.

To elucidate the association of thermolabile MTHFR with the development of coronary artery disease, we determined the thermostability of lymphocyte MTHFR in 212 patients with proven coronary artery disease and in 202 controls without clinical evidence of atherosclerotic vascular disease.

The traditional risk factors--age, sex, diabetes, smoking, hypercholesterolemia, and hypertension--were not significantly associated with the presence of thermolabile methylenetetrahydrofolate reductase.
Using discriminant function analysis, thermolabile methylenetetrahydrofolate reductase was predictive of angiographically proven coronary artery stenosis.
