Using the Chinese data from the HapMap project, a set of tagging single-nucleotide polymorphisms (tagSNPs) were defined for the DPP9 gene. Five SNPs were genotyped by PCR restriction fragment length polymorphism. Statistical analysis of genotype frequencies between cases and controls was performed by the \u03c72 test. One-way analysis of variance was used to compare mean maximum Cobb angles with different genotypes in case-only analysis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Genotype frequencies were comparable between cases and controls for all five polymorphisms (p&amp;gt;0.05).
