Two groups of human disorders involve expansion of tandem trinucleotide repeats in coding DNA to give gene products with abnormally long polyglutamine or polyalanine repeats. The pathogenic mechanisms have rather different characteristics, however in the way that the trinucleotide repeats expand. In what ways do they differ?
