A base pair deletion is a mutation where one nucleotide is removed during DNA replication. The base-pair deletions produce frameshift mutations, i.e., they cause genetic modifications that alter the Open Reading Frame (ORF) of the corresponding protein. Examples of human diseases caused by deletion mutations include, among others, cystic fibrosis and Williams syndrome.
