The strongest association signal for PTSD was found on chromosome 13 (P = 4.79 × 10–20), in a region spanning noncoding mRNAs LINC01065, PCDH8P1, and RN7SL618P as well as olfactomedin 4–encoding gene OLFM4, which takes part in innate immunity, inflammation, and cancer. The gene discussed is LINC01065; the disease is post-traumatic stress disorder.
