Researchers pinpoint dozens of genes tied to OCD and tic disorders, opening drug avenues

Researchers examined DNA from almost 4,000 individuals diagnosed with obsessive-compulsive disorder or chronic tic disorders and uncovered 36 genes that substantially raise susceptibility to these conditions. The findings, appearing in Nature Neuroscience, show extensive overlap between the two disorders and indicate that the implicated genes operate within shared neural networks, which may be exploitable for new treatments.

Jay Tischfield emphasized that moving from a few known genetic factors to more than 30 opens a broader landscape for pharmaceutical development. Several of the identified genes have prior associations with autism and schizophrenia, reinforcing the idea of intersecting psychiatric pathways. In related research published in the Journal of Clinical Investigation, scientists demonstrated that inhibiting the mitochondrial protein EFHD1 curtails inflammation and scarring in fatty liver disease models, suggesting a novel therapeutic route. Both studies highlight how deeper genetic and molecular insights can shift focus from symptom management to targeting underlying disease mechanisms.
