A recent large-scale European-originated genome-wide association data meta-analysis followed by a replication study identified 6 new risk loci for Parkinson's disease (PD), which include rs10797576/SIPA1L2, rs117896735/INPP5F, rs329648/MIR4697, rs11158026/GCH1, rs2414739/VPS13C, and rs8118008/DDRGK1.
Because ethnic-specific effect is an important concern for GWAS analysis, we genotyped single-nucleotide polymorphisms in the new genetic loci, GCH1 (rs11158026), SIPA1L2 (rs10797576), VPS13C (rs2414739), and MIR4697 (rs329648), to investigate their associations with risk of PD in Taiwan.
Our findings first demonstrated that VPS13C rs2414739, MIR4697 rs329648, GCH1 rs11158026, and SIPA1L2 rs10797576 do not confer a significant risk for PD in Chinese population.
