Researchers combined data from many different health groups around the world. They looked at rare changes in genes that might affect health. This approach helps find connections that are too small for one group to find on its own.
The team found 514 links between genes and health traits. About one-third of these links were missed when looking at just one group of people. This shows why sharing data is so important for understanding health.
They also found that 91 new links appeared only when mixing data from many groups. The effects of these genes worked the same way in different people. This gives doctors a better tool to study rare causes of common diseases like asthma and diabetes.
This work creates a free resource for scientists everywhere. It helps them study rare gene changes without needing huge single groups. This method makes it easier to find answers for many health problems.
