Chromosomal position, allele, marker location, and minor allele frequencies for the 15q25 cluster markers analyzed in this study

SNPs	Chromosome position	Allele	Location	Freq EA	Freq AA
rs951266	76665596	C/T	intron, CHRNA5	0.36	0.11
rs16969968	76669980	G/A	exon, CHRNA5, missense D→N	0.35	0.02
rs1051730	76681394	G/A	exon, CHRNA3, synon Y→Y	0.35	0.11
rs8040868	76698236	T/C	exon, CHRNA3, synon V→V	0.40	0.35
rs17487223	76711042	C/T	intron, CHRNB4	0.33	0.12

The minor allele is located on the right and bolded. Minor allele frequencies for both populations are based on the combined European-American/Irish samples and the combined African-American sample.

AA, African-American; EA, European-American; SNP, single nucleotide polymorphism.
