Meta‐analysis results did not show a significant association between the rs4998386 polymorphism of the GRIN2A gene and PD susceptibility when assuming an allelic model (OR, 0.90; 95% CI, 0.76‐1.07; P = .22; I2 = 53%), a dominant model (OR, 0.96; 95% CI, 0.82‐1.12; P = .62; I2 = 64%), or a recessive model (OR, 1.14; 95% CI, 0.93‐1.38; P = .22; I2 = 0%). Here, GRIN2A is linked to Parkinson disease.
