    Abstract:
    We evaluated the association of the platelet-activating factor receptor (PAFR) gene polymorphism (A224D) with the susceptibility and severity of multiple sclerosis (MS) in a Japanese population. DNA was collected from 162 Japanese patients with clinically definite 'conventional' MS (MS) and 245 healthy controls. The missense mutation A224D that impairs PAF-PAFR signaling was determined by polymerase chain reaction restriction fragment length polymorphism. The frequency of the AD/DD genotypes was significantly higher in MS patients (21.0%) than in healthy controls (13.5%) (p=0.045; odds ratio (OR), 1.71; 95% confidence interval (CI), 1.01-2.89). Moreover, the frequency of D allele in MS patients (11.7%) was also significantly higher than those in healthy controls (6.9%) (p=0.019; OR, 1.78; 95% CI, 1.10-2.89). These findings suggest that the PAFR gene missense mutation has a relation to the susceptibility for MS.
