title: Seventeen novel alleles add to the already extensive KIR3DL3 diversity.
abstract: Exons 2-9 of KIR3DL3 alleles were characterized by genomic DNA sequencing in two families and in 78 bone marrow transplant samples. Several strategies were used to isolate single alleles for characterization and to resolve alternative allele combinations. We describe 17 novel 3DL3 alleles carried by 30 individuals. Compared with the most closely matched alleles, the new alleles differ by from one to three nucleotides and from zero to three amino acids. The majority of the substitutions were shared with other 3DL3 alleles although three novel polymorphic codons, 151 (exon 4), 327 (exon 7) and 352 (exon 9), are described. Of the 36 different 3DL3 alleles detected in the transplant population, the three most common alleles accounting for 47% of the total were KIR3DL3*00101 (13.5%), KIR3DL3*003 (21.2%) and KIR3DL3*00901 (12.2%).
