WebParamount to this model are the residuals between expected and observed relative frequency of substitution for several Grantham difference magnitude classes. The relative effect purifying selection has on amino acid sequence evolution is quantified by calculating the sum of the positive residuals. This model is used to evaluate the differential ... WebOct 1, 2001 · Using Grantham's chemical difference matrix, we find that amino acid changes observed in disease patients are far more radical than the variation found among species and in non-diseased humans. Overall, our results demonstrate the usefulness of evolutionary analyses for understanding patterns of human disease mutations and …
