Genetic variability of the CYP 2D6 gene is not a risk factor for sporadic Parkinson's disease.
Genetic studies of the frequencies of mutant alleles for coding cytochrome P-450 monooxygenase (CYP 2D6) in Parkinson's disease (PD) patients have been inconsistent. We studied the mutants A and B in 80 strictly defined sporadic PD patients divided into young age onset of the disease (< 40 years, N = 20), mid age onset (40-50 years, N = 12), and older age onset (> 50 years, N = 48). They were compared with 108 controls from the same geographic area. There were no significant differences in allele or genotype frequencies between PD patients and controls. Future genetic studies in PD should focus on other alleles or other areas of the genome.
