Objectives To investigate the association between intercellular adhesion molecule‐1 (ICAM‐1) gene K469E polymorphism and spontaneous preterm delivery in a Korean population. Methods Genomic DNA was extracted from whole blood from 55 women experiencing preterm labor and 153 multiparous women (control group) with a history of at least 2 term deliveries. DNA samples were analyzed by polymerase chain reaction–restriction fragment length polymorphism. Results The spontaneous preterm delivery (SPD) group carried the 469E allele significantly more frequently than those in the control group (odds ratio [OR], 1.62; 95% CI, 1.04–2.53). The EE genotype was significantly associated with increased risk of SPD (OR, 2.84; 95% CI, 1.17–6.89; P = 0.02). Allelic frequencies in women with abnormal C‐reactive protein levels (K = 0.48; E = 0.52) were significantly different from frequencies in the controls (K = 0.68; E = 0.32) ( P = 0.006). Conclusions ICAM‐1 gene K469E polymorphism may be a candidate region and useful predictor of susceptibility to SPD in the Korean population.
