Amino Acid Changes in Disease-Associated Variants Differ Radically from Variants Observed in the 1000 Genomes Project Dataset
Figure 9
Bubble plots comparing the relative differences between the instantaneous rate change matrices of the data sets.
(A) 1 kG data, (B) PAM matrix and (C) WAG matrix. (D) A PCA (first two components) plot showing the separation of the 1 kG matrices from other matrices. Matrices included are 1 kG (with and without assuming direction), nuclear (WAG, JTT, LG, PAM, tm126, PCMA), mitochondrial (mtREV24, mtMam, mtArt, mtZoa), chloroplast (cpREV, cpREV64), exposed (alpha helix, beta sheet, coil, turn) and buried (alpha helix, beta sheet, coil, turn). Principal components one and two represent 34% and 20% of the variance, respectively. All other principal components represent 9% or less of the variance each. Amino acids are arranged according to increasing hydrophobicity.
