  1. a Represent frequency (%) of haplotypes; (n) indicates the number of haplotypes.
  2. b Control consists of half-sibs (see Additional File 1: Inferring allele, genotype, haplotype and diplotype frequencies from half-sibs).
  3. c P-values from χ2-test against pooled observations of all remaining haplotypes.
  4. d Odds Ratios with reference haplotype 23ins-12ins.
  5. e P-values from logistic regression, testing the risk effect compared to reference haplotype 23ins-12ins.
  6. f P-values from logistic regression, testing the risk effect compared to reference haplotype 23del-12ins.
