Long haplotypes around <i>THADA</i> in East Asian and European populations.

<p>Illustration of haplotype forms identified by haploPS that span the longest genetic distances around <i>THADA</i> (brown horizontal bar) on chromosome 2. Uncharacteristically long haplotypes were found at the same frequency of 45% in two East Asian populations (CHD, CHS) to span <i>THADA</i>, whereas at the same frequency, the longest haplotypes present in European populations (CEU, TSI, MXL) were comparatively much shorter. The haplotypes for the two East Asian populations also carried the thymine allele at rs7578597 that has been reported in association studies to increase the risk to Type 2 diabetes.
