Researchers find gene that triples risk of developing Alzheimer's disease
Group of researchers from 44 different institutions around the world, including scientists from the Mayo Clinic, the University of Toronto and the University of Nottingham have discovered a gene that triples the risk of developing Alzheimer’s disease.
The international group of scientists utilized the Nottingham ARUK DNA Bank, one of the biggest collections of DNA pooled from Alzheimer’s patients.
The team of investigators was able to piece together the new set of findings with sequencing techniques that focused on the TREM2 gene, which later lead to the identification of a group of rare variations in TREM 2 that was found more frequently in 1,092 Alzheimer’s disease patients as compared to the control group of 1,107 healthy individuals.
Dr. Peter, St George-Hyslop, Director of the Tanz Centre for Research in Neurodegenerative Diseases said, “This discovery provides an increasingly firm link between brain inflammation risk for Alzheimer’s.” He also said, “This is an important step towards unraveling the hidden causes of this disease, so that we can develop treatments and interventions to end one of the 21st century’s most significant health challenges.”
Further, in a group of follow-up studies, the researchers evaluated R47H, the most common variant. The physicians from the Mayo Clinic evaluated the patients and control group patients.
Based on the findings, it was noted that the R47H variant in TREM2 elevated the risk of developing Alzheimer’s disease significantly. “The TREM2 variant may be rare, but it is potent,” explained Minerva Carrasquillo, a scientist with the Mayo Clinic. He also said, “In our series, it was present in 1.9 percent of the Alzheimer’s patients and in only 0.37 percent of the controls. This strong effect rivals that of the well-established genetic variant known as APOE4, and it was observed both in our study and in the independent study led by decode that was published with ours. R47H isn’t fully penetrant — meaning that not all people who have the variantwill develop Alzheimer’s and in those who do, other genes and environmental factors will also play a role — but like APOE4 it does substantially increase risk.”
Rosa Rademakers, a researcher at the Mayo Clinic said, “The variant found in our study identifies a fascinating new Alzheimer’s disease gene, TREM2, which is involved in the immune system.” Rosa also said, “This fits well with other evidence linking the immune system to Alzheimer’s disease, but additional studies are needed to establish that R47H does, in fact, act by altering immune function. Fortunately, this variant changes an amino acid in TREM2 and that will greatly facilitate the biological studies that follow.”
Researchers are of the view that the study comes at an important junction in time as the cause of Alzheimer’s is still not clear. The scientists also believe that the disease is due to a complex mix of environmental and genetic factors.
Vuram launches automated app to track COVID-19 supplies
A new app that tracks COVID-19 supplies in real time time has launched.
Built by hyper-automation services company Vuram, Trackable can monitor the progress of vaccines, oxygen cylinders, PPE, and masks as they move through the supply chain.
The app's features include street view to facilitate coordination between drivers, and trained facial recognition software powered by Microsoft Azure to ensure goods are only handled by authorised personnel.
Other functions include:
* Demand management for inventories, to prioritise deliveries using automation
* Demand analysis to predict sales trends based on stock levels
* Offline multilingual feature for drivers
* A dashboard to see the status and location of drivers
* Insights on how products are performing in real-time
The team at Vuram built Trackable as part of the Appian World 2021 Online Hackathon, where participants can take their ideas for innovative software and create a custom app. The tracking app went on to win the contest.
“Custom component building is at the heart of this application, and we focussed on making them more creative to provide an improved user experience" said Santosh Kumar, co-developer of Trackable.
"We are happy that we have managed to make it to the top in just a month. On behalf of Vuram, I thank the Appian Hackathon team for their efforts in conducting the event, and my hearty congratulations to all the winners."
