At the genetic level, Qiu et al. combined the genome-wide association study with the expression quantitative trait loci to identify five m6A-related single nucleotide polymorphisms (m6A-SNPs) significantly associated with PD: rs75072999 in G-associated kinase (GAK); rs1033500 in C6orf10; and rs1378602, rs4924839, and rs8071834 in ALKBH5 [39]. The gene discussed is ALKBH5; the disease is Parkinson disease.
