Abbreviations: AF, allele frequency; BP, base pair position; CHRNA5=cholinergic receptor, nicotinic, alpha 5; C1orf100=uncharacterized chromosome 1 open reading frame; CHRNA3=cholinergic receptor, nicotinic, alpha 3; LOC503519=uncharacterized; PSMA4=proteasome (prosome, macropain) subunit, alpha type 4; SNP, single-nucleotide polymorphism.
Note: When the original STOMP (David et al.18) SNP was not available for analysis in the DNHS, a proxy SNP (r2>0.9) was used in its place; rs667282 served as a proxy for rs667282 (r2=0.924), rs7163730 served as a proxy for rs3813570 (r2=0.916).
