Genetic data from more than 200,000 people reveals PTSD, like many other psychiatric disorders, is highly polygenic. Six loci harbor variants were strongly associated with an increased risk of PTSD. The loci hints that inflammatory and immune mechanisms may be involved in the disorder. The study also revealed a significant overlap with 21 genes implicated in depression, schizophrenia, neuroticism, insomnia, asthma, and coronary artery disease.

Neuronal branches in SETD1A deficient mice are shorter and stunted. Switching off another gene, LSD1, nullifies the harmful effects of SETD1A on neuron and axon growth. After inhibiting LSD1, SETD1A deficient mice showed improved memory and axon growth. Inhibiting LSD1 not only acted on memory deficits linked to schizophrenia but also acted on the underlying molecular mechanisms associated with axonal growth.

Mu-opioid receptor (MOR) levels are significantly reduced in the striatum in those with schizophrenia. A lack of MOR system stimulation contributes to negative feelings, such as a lack of motivation and anhedonia, associated with the condition. Increasing MOR levels could help to reduce some of the symptoms of schizophrenia.
