Associations of the top nicotine dependence-associated SNP rs2273500 with transcript-level and exon-level CHRNA4 mRNA expression in intralobular white matter from 134 European-ancestry participants in the UK Brain Expression Consortium. The probe size (in base pairs) is indicated, and P-values <0.05 are shown in bold. SNP, single nucleotide polymorphism.
