Abstract:
Parkinson's disease (PD) is a common neurodegenerative disease with inherent sex differences, and sex-determining region Y (SRY) is a gene located in the Y chromosome which encodes a transcription factor involving the regulation of the dopamine system. In this study, we investigated whether SRY variants were associated with PD in Chinese population. A total of 2058 male patients with PD and 1650 male control participants were recruited, and variants in SRY transcript and flanking regions were genotyped by whole-exome sequencing or whole-genome sequencing. Analysis of rare variants by the optimal sequence kernel association test showed no difference in variant burden of coding, 5'-noncoding and 3'-noncoding between the case and control group. In addition, of the 6 common variants identified, none showed a significant effect in altering PD risk in our population using logistic regression. Our results suggested SRY variants were not associated with the risk of PD in Chinese population.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
