- Initial treatments show promise with L-serine.
New Delhi, Nov 15 (NationPress) Researchers from Germany have discovered a gene linked to schizophrenia and various mental disorders.
Previously, it was believed that conditions like schizophrenia, anxiety disorders, and depression stem from a combination of multiple factors, including genetic influences.
The findings, published in the journal Molecular Psychiatry, pinpoint the GRIN2A gene as a significant contributor. The research revealed that alterations in GRIN2A can directly result in schizophrenia.
Lead researcher Professor Johannes Lemke, who serves as the Director at the Institute of Human Genetics at the University of Leipzig Medical Centre, stated, "Our findings reveal that GRIN2A is the first identified gene that can independently cause a mental illness, setting it apart from the previously assumed polygenic origins of these disorders."
The study involved analyzing data from 121 subjects with genetic variations in the GRIN2A gene.
"We demonstrated that specific variants of this gene are linked not only to schizophrenia but also to other mental health conditions,” said Lemke.
Interestingly, disorders associated with GRIN2A mutations often manifest in childhood or adolescence, contrasting with the typical adult onset, Lemke noted.
Some individuals affected displayed solely psychiatric symptoms, whereas GRIN2A mutations are typically seen alongside conditions such as epilepsy or intellectual disability.
The GRIN2A gene is crucial in modulating the electrical activity of nerve cells. In this research, particular variants diminished NMDA receptor activity, a pivotal component in brain signaling.
In preliminary treatment trials, patients experienced significant improvements in psychiatric symptoms after receiving L-serine, a dietary supplement that enhances NMDA receptor activation.
The World Health Organization (WHO) reported that in 2021, nearly one in seven individuals worldwide battled a mental illness, with anxiety disorders and depression being the most prevalent.
Mental disorders generally arise from complex factors, with a substantial genetic element. This new study could lead to advancements in early diagnosis and intervention.
Point of View
I see this discovery about the GRIN2A gene as a significant advancement in mental health research. It opens avenues for deeper understanding and potential early interventions for mental illnesses. With mental health issues on the rise globally, this research is timely and critical, underscoring the need for ongoing exploration in the field.
