— indicates not applicable; ? indicates unknown mutation effect.
Protein nomenclature is given considering the Ile of the mature NE as the first amino acid; mature enzyme is composed of 218 amino acids; amino- and carboxy-terminal domains are peptides of 29 and 20 residues, respectively
Phenotype 1 refers to SCN and 2 refers to CN, main phenotype associated to the mutation is numbered first
Novel mutation
