‘Unraveling the Un-Aliving Enigma’ – Suicide Risk Factors lie in our DNA

In a groundbreaking discovery, a global coalition of brilliant minds in science has unearthed a dozen elusive DNA variants tightly linked to suicide attempts. This research brings us closer to finding medicine that will prevent this heart-wrenching tragedy.

Dark Mystery

Suicide has long been a dark mystery with little scientific explanation. Now, a group of scientists have finally cracked it open and revealed some of its secrets.

What they found out might surprise you. 

Impulsivity, smoking, chronic pain, pulmonary conditions, ADHD, and heart disease have been genetically linked to suicide.

Docherty says. “It showed significant overlap with mental health conditions, but also a lot of physical health conditions, particularly for smoking and lung-related illnesses.”

The genetic variants linked to suicide attempts surpassed the boundaries of mental health alone.

The Cumulative Genetic Effect 

It was linked with an array of other health conditions, from psychiatric disorders to physical ailments and even behaviors. The genetic risk for suicide intertwines with a myriad of health factors. 

Suicide has many layers. A single genetic factor does not control it but is rather orchestrated by a symphony of genetic factors.

Digging deeper into the intricate genetics of suicide requires an innovative approach. Suicide’s genetic footprint is trackable within our genetic map. Dr. Anna Docherty explains how “tiny genetic effects when aggregated, form a potent genetic risk.”

This nuanced understanding is vital in unraveling the genetic intricacies of suicide.

Making the Discovery 

The huge size of this genetic investigation was the result of a remarkable collaboration among renowned institutions worldwide, including the Huntsman Mental Health Institute and Icahn School of Medicine at Mount Sinai, just to name a couple.

United, they meticulously dissected data from diverse global populations. To understand the genetic variants, researchers applied sophisticated statistical techniques to a vast dataset, merging information from the Million Veteran Program (MVP) and the International Suicide Genetics Consortium (ISGC).

This monumental effort incorporated 43,871 documented suicide attempts and 915,025 ancestry-matched controls.

New Avenues for Suicide Prevention

Identifying genetic links between suicide and various health factors opened new doors for assessing and mitigating suicide risk.

Dr. Docherty envisions these findings as a starting point for identifying promising drug targets to enhance suicide prevention efforts. When it comes to suicide, one constant prevails.

The power of knowledge to reshape our understanding and experiences.

The genetic study of suicide opens new avenues for prevention.

Many of the identified genes control critical cellular processes, such as stress management, DNA repair, and immune system communication.

Potential Clues to Intervention

These genes are predominantly active in the brain and are targets of psychotropic medications. While the study establishes associations between genetic variants and suicide risk, it still doesn’t prove causation.

Further research is required to ascertain the precise mechanisms linking these genetic variations to suicide attempts.

Hillary Coon, Ph.D., co-author of the study and professor of psychiatry at HMHI, notes that having these conditions don’t automatically put you in a high risk of suicide category.

Docherty says, “We want to start to explore the biological underpinnings that are common across suicide and these health factors because that will lead to the most convincing drug targets.”
