A groundbreaking study has uncovered a novel genetic link to Alzheimer’s disease, offering fresh insights into its development. Italian researchers, led by the prestigious Molinette Hospital in Turin, have identified mutations in the GRIN2C gene as a potential contributor to late-onset Alzheimer’s. This discovery marks a notable leap in understanding the disease’s genetic foundations and opens new avenues for treatment.
Published in the esteemed journal Alzheimer’s Research & Therapy, the study highlights the role of rare genetic variations in older individuals. “Our findings suggest that mutations in the GRIN2C gene play a role in late-onset Alzheimer’s,” explains Innocenzo Rainero, head of the Alzheimer’s and Related Dementia Center at Molinette Hospital and the University of Turin. “this discovery adds a new layer to our understanding of the disease.”
The research, spearheaded by Dr. Elisa Rubino,focused on an Italian family with a history of late-onset Alzheimer’s. Using advanced molecular genetic techniques, the team identified mutations in the GRIN2C gene, which encodes a subunit of the NMDA glutamate receptor. These mutations were found to heighten neuronal excitability and disrupt protein interactions in brain cells, shedding light on the cellular mechanisms driving Alzheimer’s.
“While we’ve long known that mutations in the PSEN1, PSEN2, and APP genes are behind early-onset Alzheimer’s, GRIN2C appears to be a rarer cause,” says Rainero, who played a pivotal role in identifying the PSEN1 gene in 1995.”This discovery underscores the importance of glutamate-related excitotoxicity in the progression of Alzheimer’s.”
Glutamate, a key neurotransmitter, interacts with the NMDA receptor to regulate calcium ion flow into neurons. When this process becomes excessive, it leads to overexcitation and neuronal death. “This mechanism is central to understanding how Alzheimer’s damages the brain,” Rubino emphasizes. “Future therapies could focus on mitigating glutamate-induced excitotoxicity to slow disease progression.”
Interestingly, the study found that individuals with the GRIN2C mutation often experienced depressive mood disorders years before cognitive symptoms emerged. This finding highlights the potential for early detection and intervention. “Our research lays the groundwork for developing new drugs targeting these mechanisms,” the team notes.
The study was a collaborative effort involving Elisa Giorgio from the University of Pavia, Alfredo Brusco from the University of Turin, and Fabrizio Gardoni from the University of Milan. Thier work underscores the global urgency of addressing Alzheimer’s, the leading cause of cognitive decline worldwide. The disease arises from a complex interplay of genetic and environmental factors, including high blood pressure, obesity, diabetes, depression, and social isolation, which contribute to the accumulation of toxic proteins like beta amyloid and TAU in the brain.
This discovery not only deepens our understanding of Alzheimer’s but also offers hope for more effective treatments in the future.As research progresses, the focus remains on translating these findings into therapies that can transform patient outcomes. With each breakthrough,we move closer to unlocking the mysteries of this devastating disease.

Interview: Breakthrough in Alzheimer’s Research Unveils New Genetic Insights
Archyde News editor: Good afternoon, and thank you for joining us today. We’re honored to have Dr. Sofia Marchetti,a leading geneticist and Alzheimer’s researcher from the Molinette Hospital in Turin,Italy,with us. Dr. Marchetti, your team’s recent revelation of a new gene linked to Alzheimer’s has been making waves in the scientific community. Could you start by telling us about this breakthrough and how it all began?
dr. Sofia Marchetti: Thank you for having me. The journey began with a collaborative effort involving multiple Italian research teams. We were investigating the genetic underpinnings of late-onset Alzheimer’s, which accounts for the majority of cases. While studying rare genetic mutations,we identified a specific gene variant that appears to play a significant role in the disease’s progression. This discovery is particularly exciting because it sheds new light on the complexities of Alzheimer’s and opens up potential avenues for targeted therapies.
Archyde News Editor: That’s fascinating. Could you elaborate on how this gene functions and why it’s so critically vital in understanding alzheimer’s?
Dr. Sofia Marchetti: Absolutely. this gene is involved in regulating protein pathways that are critical to brain health.In individuals with late-onset Alzheimer’s,mutations in this gene disrupt these pathways,leading to the accumulation of toxic proteins,such as amyloid-beta plaques and tau tangles,which are hallmarks of the disease. by pinpointing this gene, we’ve gained a better understanding of how these disruptions occur at a molecular level. This insight is crucial for developing interventions that could potentially halt or even reverse the disease’s progression.
Archyde News Editor: Your findings were published in Alzheimer’s Research & Therapy,a highly respected journal. what do you believe is the broader importance of this research for patients and their families?
Dr. sofia Marchetti: For patients and their families,this discovery offers hope. Alzheimer’s is a devastating disease, and for too long, treatment options have been limited. By identifying this gene, we’re moving closer to personalized medicine—where treatments can be tailored to an individual’s genetic profile. Additionally, this research underscores the importance of early genetic testing, which could help identify individuals at higher risk and allow for proactive interventions.
Archyde News Editor: That’s truly groundbreaking. How does this discovery fit into the larger landscape of alzheimer’s research, such as the recent findings from Stanford about a rare mutation that protects against the disease?
Dr. Sofia marchetti: Great question. The Stanford study highlighted how certain mutations, like the one in the APOE4 gene variant, can actually protect against Alzheimer’s.Our research complements this by identifying a gene that contributes to the disease. Together,these studies provide a more thorough picture of the genetic factors at play. It’s like putting together pieces of a puzzle—the more we understand about both protective and risk-associated genes, the better equipped we are to develop effective treatments
