How Similar Are Amino Acid Mutations in Human Genetic Diseases and Evolution

Accumulating evidence indicates that some deleterious mutations responsible for genetic diseases may offer benefits for human to prevent other diseases. Therefore, human genetic diseases and evolution were tentatively regarded as the two sides of the same coin, which stimulated our interest to explore how similar are amino acid mutations in human genetic diseases and evolution. Through a large-scale analysis on amino acid mutation patterns of genetic diseases and evolution of Hominidae (Homo sapiens and Pan troglodytes), it was found that there exist significant correlations between two mutation patterns. Besides, there also exist some evident differences between both mutations, especially those associated with four amino acids C, G, R, and L. These findings are of significance to understanding the subtle connections between human genetic diseases and evolution.
