Supplementary Figure 8: Multidimensional scale–based principal-component analysis.
From: Genetic association analyses highlight biological pathways underlying mitral valve prolapse
Cases and controls positions on first and second components axis are presented for the two discovery samples (GWAS 1 and GWAS 2). C1, first principal component. C2, second principal component. All individuals plotted are those included in the discovery GWAS who are all French with European ancestry origin. Cases and controls with non-European ancestry based on the principal component analyses were excluded before association tests.
