TAP1 and TAP2 are two major histocompatibility complex (MHC) genes, located between HLA-DP and -DQ, whose products form a transporter molecule involved in endogenous antigen processing. Polymorphic residues have been described in both genes and, in this study, we have identified another polymorphic site within the adenosine triphosphate (ATP)-binding domain of TAP2. We have used the amplification refractory mutation system (ARMS) polymerase chain reaction (PCR) to characterize TAP1 and TAP2 alleles and haplotypes in a reference panel of 115 homozygous typing cell lines. Of four possible TAP1 alleles, we observed three, and of eight possible TAP2 alleles, we observed five. Among 88 (homozygous typing cells) (HTCs) homozygous at HLA-DR, -DQ and -DP, 80 were also homozygous at TAP1 and TAP2. Of 27 HTCs homozygous at HLA-DR and -DQ, but heterozygous at -DP, 14 were homozygous at TAP1 or TAP2 and 13 heterozygous, consistent with recombination taking place either side of the TAP loci. Of the fifteen possible combinations of TAP1 and TAP2 alleles, we observed eleven, each at a frequency similar to that predicted by individual allele frequencies. In this ethnically heterogenous panel there is no indication that particular combinations of TAP1 and TAP2 have been maintained together.
