Homocysteine levels have been investigated in patients with obstructive sleep apnoea syndrome (OSAS), a syndrome associated with a high level of comorbid cardiovascular disease (CVD). While significant increases in homocysteine levels have been observed in OSAS patients with CVD, no increases have been noted in OSAS patients without CVD. This study was designed to investigate the methylenetetrahydrofolate reductase (MTHFR) gene, which is essential for homocysteine metabolism and has been shown to have a causal role in the development of CVD. Eighty subjects, 30 diagnosed with OSAS by polysomnography and 50 controls (healthy volunteers with no symptoms of OSAS) were enrolled. Two mutations in the MTHFR gene were investigated using polymerase chain reactions and restriction fragment length polymorphisms. No significant differences were found in mean age, body mass index, homocysteine levels, or MTHFR allele or genotype distributions between patient and control groups.
