For instance, MX dynamin-like GTPase 1 (MX1) and type I interferon (IFN) are suggested as latent biomarkers for the activity of SjS and SLE diseases (51, 52), and IFI44L is also referred to as a signatory gene of the type I IFN signaling (53). This evidence concerns the gene MX1 and Schwartz-Jampel syndrome.
