The invention provides an improved method for typing specific HLA sequences and other genetic sequences exhibiting similar polymorphism may be detected by sequence specific amplification (SSA). In essence, the primers used to carry out the amplification are chosen to represent sequences that distinguish one allele from another. As a result, the allele is detected if amplification occurs, and is absent if no amplification occurs. This technique can eliminate the need to conduct sequence-specific probe hybridization in order to distinguish among closely similar alleles, and can, in particular, allow resolution of complementary pairs of naturally-occurring HLA alleles which have the same polymorphisms but located on different individual alleles of each pair.
