M: More than three mutation sites. Amino acid change: H: Histidine (HIS); Y: Tyrosine (TYR); G: Glycine (GLY); E: Glutamic (GLU); N: Asparagine (ASN); S: Serine (SER); T: Threonine (THR); A: Alanine (ALA); Q: Glutamine (GLN); V: Valine (VAL); D: Aspartic (ASP); +S: add a Serine (SER); +L: add a Leucine (LEU); I: Isoleucine (ILE). -: Not available
