Genes that breach immune tolerance and promote autoantibody production have also been investigated as part of the complex mosaic underlying SLE development, as they have been shown to influence innate immune signaling and type I interferon (IFN) production, which in turn can generate an influx of effector leukocytes, inflammatory mediators, and autoantibodies toward involved organs, such as the kidneys. Here, IFNA1 is linked to systemic lupus erythematosus.
