Diversity across KIR haplotypes stems from differences in numbers of inhibitory and activating receptors, as well as allelic polymorphism of individual genes. The KIR locus has undergone large expansions and contractions over time and is believed to be coevolving with genes encoding its HLA class I ligands located within the MHC locus. KIR and HLA compound genotypes have been associated with susceptibility to or protection from infectious, autoimmune, reproductive, and malignant disorders. We describe here a simple and reliable multiplex PCR-SSP (sequence-specific priming) method for relatively rapid and inexpensive genotyping of 15 KIR genes using standard agarose gel electrophoresis.
KIR单倍型的多样性源于抑制性和激活性受体数量的差异,以及单个基因的等位基因多态性。随着时间的推移,KIR基因座经历了大规模的扩张和收缩,并且被认为与位于MHC基因座内编码其HLA I类配体的基因共同进化。KIR和HLA复合基因型与感染性、自身免疫性、生殖性和恶性疾病的易感性或保护性相关。我们在此描述一种简单可靠的多重PCR-SSP(序列特异性引物)方法,用于使用标准琼脂糖凝胶电泳对15个KIR基因进行相对快速且廉价的基因分型。
