LILRB1 Gene

What is the LILRB1 gene?

LILRB1 encodes leukocyte immunoglobulin like receptor b1 (ilt2/cd85j), a protein involved in NK and T cell inhibitory signaling. It belongs to the Immune Signaling category and is part of the HLA & Immune Presentation biological cluster. LILRB1 encodes ILT2/CD85j, an inhibitory receptor on NK cells, B cells, and monocytes that recognizes HLA class I molecules.

Biological role and pathway

LILRB1 is involved in the NK and T cell inhibitory signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the HLA & Immune Presentation cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the LILRB1 gene have been studied in relation to immune signaling and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
