Subjects distribution according to the PCA analysis. We employed Smartpca from EIGENSOFT package and K-means method from Weka to classify all 210 subjects into 4 clusters. Different colors indicated different clusters. Triangle indicates case subjects. Crossover indicates control subjects. Principal component 1 (PC1) and principal component 2 (PC2) were the first two axes of PCA and represented 7.626% and 5.276% variance.
