| SNP – single-nucleotide polymorphism; CHR – chromosome; Ref allele – alleles in the on the reference sequence; Alt allele – the other (alternative) allele on the locus of the Ref allele; MAF – minor allele frequency (data from 1000 Genomes); HWE – Hardy-Weinberg equilibrium; P for HWE – -value for HWE in 2 groups; – -value for allele frequency differences between the 2 groups. | ||||||
