KIR2DL2 allele typing method. (A) Alignment of the amino acid sequences of the 13 known KIR2DL2 allelic variants. A dash indicates identity with the consensus KIR2DL2*003. Structural domains are indicated: Ig-like domains (D1 and D2), stem domain (ST), transmembrane domain (TM), and cytoplasmic domain (CYT). Four PCR reactions separate the three subgroups identified by phylogenetic analysis. Two additional PCR reactions separate alleles within subgroups. Frequencies of the alleles present in the learning cohort of 426 individuals and in the testing cohort of 260 individuals are indicated. The group identification of each allele is indicated. The alleles tested by PCR are in bold black font, and non-tested alleles are in gray italics. (B) KIR2DL2 PCR interpretation guide. PCR profiles marked by *, #, $ or & are similar and require a higher resolution of genotyping using supplemental reactions.
