Background:
The RAB32 Ser71Arg variant has been identified as a novel risk locus for Parkinson's disease (PD) in North American, European and North African populations. However, its pathogenicity in Asian populations remains unclear.
Method:
To investigate this, we screened for the RAB32 c.213C > G (Ser71Arg) variant using Sanger sequencing in 1,099 PD patients and 1,549 controls. And we search for the RAB32 Ser71Arg variant in public databases to identified its mutant frequency.
Results:
Our results show that no individuals carrying the RAB32 Ser71Arg variant were identified in our cohort. Additionally, this variant rarely appears in Asian population databases.
Conclusion:
Our findings suggest that the RAB32 Ser71Arg variant is unlikely to be a risk locus for PD in Chinese patients, which is potentially attributed to racial or ethnic differences.
