“…It has been reported that some polymorphisms are associated with the risk of PD, such as Rep1, rs356165, and rs11931074 in SNCA gene (Mueller et al, 2005;Satake et al, 2009;Simón-Sánchez et al, 2009;Tan et al, 2010a); G2385R and R1628P in LRRK2 gene Tan et al, 2010aTan et al, , 2010b; rs242562 and rs2435207 in MAPT gene (Skipper et al, 2004;Vandrovcova et al, 2009); and L444P in GBA gene (Sidransky et al, 2009;Sun et al, 2010). More recently, genomewide association studies (GWASs) of complex diseases have identified sequence variants that are consistently associated with the risk of such diseases.…”
