Individuals in this analysis were restricted to those in whom a PCR fragment was amplified with NA2-specific primers (84% of AA and 90% of CA). SfaN1 digestion of amplicon generated with NA2-specific oligonucleotide primers was analyzed by agarose gel; digestion by SfaN1 indicates the presence of the SH-FcγRIIIb sequence. The difference between the 2 groups was significant at P < .0001.
