Killer cell immunoglobulin‐like receptor three domains long cytoplasmic tail 1 gene *007 may modulate disease progression of human immunodeficiency virus‐1 infection in the Japanese population

One of the KIR allele, KIR3DL1*007, was associated with the progression to acquired immunodeficiency syndrome and not with the susceptibility to HIV-1 infection in the Japanese and Indian populations, implying that KIR3DL1*007-positive NK cells might eliminate HIV-infected cells less effectively than NK cells bearing the other KIR3DL1 alleles or KIR3DS1 alleles.
