OBJECTIVE: To investigate the association of variants of the fatty
acid-binding protein (FABP) 2 gene with coronary heart disease (CHD) in
nondiabetic subjects and in patients with NIDDM. RESEARCH DESIGN AND
METHODS: Cross-sectional study included 135 nondiabetic and 79 NIDDM
subjects with stenosis (> 50%) in at least two coronary arteries. A
group of 81 healthy nondiabetic men without CHD served as a control
population. All exons and intron-exon junctions of the FABP2 gene were
amplified with the polymerase chain reaction, and variants were screened
with the single-strand conformation polymorphism analysis. RESULTS: The
allele frequency of an amino acid polymorphism (alanine-->threonine) in
codon 54 of exon 2 of the FABP2 gene was 0.26 in nondiabetic subjects with
CHD and 0.27 in NIDDM subjects with CHD. Other variants (GTA 118 GTC,
GCGCA-->GCACA in the 3'-noncoding region, and the number of ATT repeats
in intron 2) also did not associate with CHD. CONCLUSIONS: The variants of
the FABP2 gene are not likely to contribute to the risk of CHD in Finnish
nondiabetic and NIDDM subjects.
