Summary
Cytochrome P-450dbl gene (CYP2D6) Xba I genotypes were investigated in 43 unrelated healthy Japanese and 51 patients with idiopathic Parkinson’s disease (IPD), using genomic DNA hybridization analysis with a cDNA probe encoding cytochrome P- 450dbl. Restriction fragment length polymorphisms (RFLPs) were observed in both populations, but the frequencies of alleles detected by restriction enzyme Xba I differed significantly. The relative risk of IPD is 2.15 times greater for idividuals with a Xba I 44 kb allele compared to those without the allele (x2 = 4.149, d.f. = 1, p < 0.05). Furthermore, the relative risk of IPD is 6.32 times greater for the Xba I 44 kb homozygotes than the Xba I 29 kb homozygotes (x2 = 4.935, d.f. = 1, p < 0.05). These data suggest that the Xba I 44 kb allele of CYP2D6 is one of the genetic factors making humans susceptible to IPD acquisition.
