TREX1 stands for Three Prime Repair Exonuclease 1, which is a gene that provides instructions for making an enzyme involved in DNA repair. This enzyme helps maintain the integrity of our genetic material by removing unwanted DNA fragments. When the TREX1 gene mutates or changes, it can lead to the malfunction of this enzyme, resulting in the buildup of DNA fragments that can trigger immune responses and cause various health issues.
Pathophysiology of TREX1 Mutation Diseases
Pathophysiology refers to how a disease develops and affects the body. In TREX1 mutation diseases, changes in the TREX1 gene disrupt normal cellular functions, leading to a cascade of effects.
Structure
- Gene Structure: The TREX1 gene is located on chromosome 3 and encodes the TREX1 enzyme.
- Enzyme Function: TREX1 is crucial for degrading excess DNA in cells, preventing inappropriate immune activation.
Blood
- Immune System Activation: Accumulated DNA fragments can activate the immune system, leading to inflammation.
- Autoimmune Response: The body may mistakenly attack its own tissues, causing autoimmune diseases like lupus.
Nerve Supply
- Neurological Impact: Some TREX1 mutations affect the nervous system, leading to neurological symptoms such as headaches, seizures, and cognitive impairments.
- Peripheral Nervous System: Damage can occur in the peripheral nerves, causing pain, numbness, or weakness in limbs.
