Amino acid substitutions in the human genome: evolutionary implications of single nucleotide polymorphisms.

Abstract excerpt

Functional differences between amino acids have long been of interest in understanding protein evolution. Several indices exist for comparing residues on the basis of their physicochemical properties and frequencies of occurrence in conserved protein alignments. Here we present a residue dissimilarity index based on coding single nucleotide polymorphisms (SNPs) in the human genome. The index represents an...
