  1. *Novel mutation.
  2. Nucleotide numbers are based on the full sequence published by O’hara et al 1987 using the A of the ATG initiator methionine as +1. Numbering of the amino acids is based on Genebank file NM-000131. Methionine is numbered as −60.
  3. Polymorphisms: M1: Arg at position 353, M2: Gln at position 353. P0: no insertion of 10 bp at position-323 in promoter, P10: insertion of 10 bp at position-323 in promoter. A1: nt C at position −122 in promoter, A2: nt T at position −122 in promoter.
  4. ND: not determined.
