d eletion only

If UUA codes for leucine (leu), UUU codes for phenylalanine (phe), AUU codes for isoleucine (iso), AAA codes for asparagine (asn), and UAA codes for a stop codon, which type of mutation would be responsible for changing the protein sequence from leu-phe-iso-iso-stop to leu-phe-leu-phe-asn-stop?
