TYK2 encodes tyrosine kinase 2, a non-receptor tyrosine kinase that belongs to the Janus kinase (JAK) family. TYK2 is a key component of type I and type III cytokine receptor signaling. It mediates signaling for interferons (IFN-α, IFN-β), IL-10, IL-12, and IL-23 receptors. TYK2 activation leads to STAT phosphorylation and downstream gene transcription. In the nervous system, TYK2 regulates neuroinflammation, microglial activation, and neuronal survival.
Widely expressed in immune cells including microglia, macrophages, and lymphocytes. Lower expression in neurons and astrocytes.
| Disease | Variants | Inheritance | Mechanism |

| Alzheimer's Disease | P1104A | Risk factor | Altered neuroinflammation |
| Parkinson's Disease | I684S | Risk factor | Modulated microglial response |
| Multiple Sclerosis | R357W | Protective | Altered cytokine signaling |
| ALS | A53T | Risk factor | Enhanced inflammation |
