ATP13A2 Gene Variants in Patients with Parkinson’s Disease in Xinjiang

Abstract EN

Objective.

To analyze the ATP13A2 gene variants in the Han and Uyghur populations residing in Xinjiang and to determine their correlation with the risk of Parkinson’s disease (PD).

Methods.

Four ATP13A2 SNVs—rs56367069 (Arg294Gln), rs151117874 (Thr12Met), rs147277743 (Ala746Thr), and rs2076603—were analyzed in 218 patients (75 Uyghurs and 143 Hans) with sporadic PD and 234 healthy controls (90 Uyghurs and 144 Hans) by Sanger DNA sequencing.

Results.

Only one Han patient harbored the AG genotype of the rs147277743 SNV, indicating a frequency of 0.46% in the Han population.

In addition, this SNV was not associated with PD risk.

The rs2076603 SNV was correlated with PD development, and the A allele in particular was significantly different across ethnicity and age.

The rs56367069 and rs151117874 SNVs were not detected in the entire cohort.

Conclusion.

ATP13A2 rs2076603 SNV is associated with PD susceptibility, and the A allele is a PD protective factor in the Han population.
