  • a The number in parentheses indicates the number of base pairs different from the proband sequence (17). BZ652 has five base pair differences that produce three amino acid differences. All these alleles express serine at amino acid residue 195. BZ1048 was not analyzed because its PCR did not work.

  • b BZ652 was initially typed as NT but was typed as weakly 6A upon reexamination.
