A relatively larger PD cohort was genetically investigated in Uzbekistan by Raimova et al. [15, 17] where 153 PD patients and 80 healthy controls were tested for Ala53Thr mutation in SNCA gene, T240M mutation in Parkin gene, G2019S mutation in LRRK2, C282T polymorphism in Nat2 gene, and polymorphisms in GSTT1/GSTM1 genes. The gene discussed is LRRK2; the disease is Parkinson disease.
