The potential relevance to alcohol responses of GABRA1 (chromosome 5q34) variants comes from animal knockout, gene expression, and between-strain animal studies (e.g., Hanchar et al., 2005; Loh and Ball, 2000), as well as a human genome-wide association study (GWAS) using single dose oral alcohol (Wilhelmsen et al., 2003). Dick et al. (2006b) reported that SRE-based low LR was related to rs1037715.
