The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC).

[6] KIR2DS4 has unusual HLA-I specificity binding some HLA-C allotypes and HLA-A*11.

[6] A common allele of KIR2DS4 encodes a truncated version (KIR-1D) that has no HLA-I binding ability.
