  1. The minor allele frequency (MAF) of rs991316 from the 1000 Genomes project (1000GENOMES_AF) was obtained from the dbSNP website ( The MAFs for the HapMap ethnicities were obtained from the International HapMap Project website ( Genotypes for the present study are listed in the order: homozygous_minor/heterozygous/homozygous_major. Abbreviations: MAF = minor allele frequency; HWE = Hardy-Weinberg equilibrium; HapMap MAFs: MEX = Mexican ancestry in Los Angeles, California; CEU = Utah residents with Northern and Western European ancestry; AFR = average MAF of ASW (African ancestry in Southwest USA), LWK (Luhya in Webuye, Kenya), MKK (Maasai in Kinyawa, Kenya), and YRI (Yoruban in Ibadan, Nigeria); ASIAN = average MAF of CHB (Han Chinese in Beijing, China), CHD (Chinese in Metropolitan Denver, Colorado), and JPT (Japanese in Tokyo, Japan).
