CD40LG encodes CD40 ligand, which binds CD40 and supports communication needed for effective antibody responses. It is on the X chromosome, which changes how some genetic results must be interpreted.

CETP transfers cholesteryl esters between lipoprotein particles. This helps explain why the balance of HDL and other lipid particles is more complex than a single cholesterol number.

CXCL13 is a chemokine that attracts cells expressing CXCR5, including B cells. This pairing helps organize immune-cell traffic in lymphoid tissues and some chronic inflammatory settings.

CXCL8 is the gene for IL-8, a chemokine involved in recruiting and activating neutrophils. IL-8 is the protein nickname; CXCL8 is the gene name a DNA report may use.

CXCR5 encodes the receptor for CXCL13. This receptor helps guide B cells and certain T cells toward locations where organized immune responses develop.

DDAH1 encodes an enzyme that breaks down asymmetric dimethylarginine, or ADMA. ADMA inhibits nitric oxide synthase; DDAH1 is part of its clearance system, not the inhibitor itself.

F5 encodes coagulation factor V. The well-characterized Factor V Leiden variant, rs6025, can make factor V less responsive to an anticoagulant control mechanism, increasing susceptibility to venous clots. It does not mean the body cannot make factor V.

F9 encodes coagulation factor IX. Disease-causing variants can result in hemophilia B, an inherited bleeding disorder, but a panel marker is not equivalent to a confirmed disease-causing finding.

GSTO2 encodes glutathione S-transferase omega 2, a redox enzyme with dehydroascorbate reductase activity that connects glutathione chemistry with vitamin C recycling. It is a separate gene from GSTO1.

HMGB1 normally has functions inside the cell nucleus. When released outside cells in particular settings, it can act as a damage-associated molecular pattern, or DAMP, participating in inflammatory signaling.

IFNG encodes interferon gamma, a cytokine involved in cellular immune defense and activation of macrophages. It differs from the Th2 signals more often emphasized in allergic responses.

IL10 encodes interleukin-10, a cytokine that can limit inflammatory responses and help prevent excessive immune-mediated tissue damage. Immune balance includes resolving a response as well as starting one.
