Abstract
Background: Insertions and deletions of DNA segments (indels) are together with substitutions
the major mutational processes that generate genetic variation. Here we focus on recent DNA
insertions and deletions in protein coding regions of the human genome to investigate selective
constraints on indels in protein evolution.
Results: Frequencies of inserted and deleted amino acids differ from background amino acid
frequencies in the human proteome. Small amino acids are overrepresented, while hydrophobic,
