The dominant model of the rs8005172 of GALC, with or without adjustment as well as the recessive model of the rs8005172 of GALC, after adjustment, were both associated with PD (dominant model: p = 0.014, OR = 2.22; p = 0.011, OR = 2.39, after adjustment; recessive model: p = 0.046, OR = 1.48, after adjustment). This evidence concerns the gene GALC and Parkinson disease.
