LZTFL1 Gene

What is the LZTFL1 gene?

LZTFL1 encodes leucine zipper transcription factor like 1, a protein involved in STING/innate immune signaling. It belongs to the Immune Signaling category and is part of the Viral Defense & Interferon Response biological cluster. LZTFL1 is located in the 3p21.31 chromosomal locus, a major COVID-19 susceptibility region identified in GWAS studies.

Biological role and pathway

LZTFL1 is involved in the STING/innate immune signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Viral Defense & Interferon Response 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 LZTFL1 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.

• rs73064425— LZTFL1 variant
• rs10490770— LZTFL1 variant
