In Past PTSD ≤ 5 y, low IL-10 (10–491.82 ng/L) indicates suppressed anti-inflammatory activity, likely driven by trauma-induced dysregulation, correlating with impaired adaptive coping (e.g., Problem-Focused: 10–16/32) and elevated avoidance (21–29/32). The gene discussed is IL10; the disease is post-traumatic stress disorder.
