Amino acid substitution (e.g. D111E) - The first letter is the one letter code of the wild type amino acid, the number is the position of the amino acid from the N terminus, and the second letter is the one letter code of the amino acid present in the mutation. Nonsense mutations are represented with an X for the second amino acid (e.g. D111X). source: http://en.wikipedia.org/wiki/Mutation
