1 Searching for variants with evidence of regulatory functions, we have reported interactions between CHRNA5 and CHRNA3 enhancer variants (tagged by rs880395 and rs1948, respectively) and rs16969968, forming 3-SNP haplotypes and diplotypes that may more accurately reflect the cluster"s combined effects on nicotine dependence (Barrie et al., Hum Mutat 38:112-9, 2017). Nicotine cholinergic receptor nicotinic alpha 3 subunit Homo sapiens
2 CONCLUSIONS: These results indicate rs4887074 is associated with CHRNB4 expression, and along with two regulatory variants of CHRNA3 and CHRNA5, modulates the effect of rs16969968 on nicotine dependence risk. Nicotine cholinergic receptor nicotinic alpha 3 subunit Homo sapiens
