Figure 2. Correlation analysis for the rs640249 polymorphism in two different reference populations.

Genotype data from the European reference population (CEU) and from the West Africa reference population (YRI) were downloaded from HapMap. A 2 Mb region surrounding the ACTC1 gene was analyzed in these two populations. The data were analyzed with Haploview Software. A) Correlations were assessed by calculating r² values. The rs640249 polymorphism was found to be correlated with three other polymorphisms in the CEU reference population (rs641563; rs639735; rs479623). B) In the West Africa reference population, the rs640249 polymorphism was correlated only with rs641563.
