## Study Finds DNA Pattern
Researchers discovered a DNA sequence repeat in the FAM193B gene may increase Alzheimer’s disease risk.
## Higher Odds in Chinese Cohort
Chinese participants with 18+ CCG repeats had twice the odds of Alzheimer’s compared to those with 11 or fewer repeats.
## Weaker Link in Europeans
European participants showed a weaker association with the same DNA pattern, though it was still identified.
## Published in Nature Neuroscience
The study was published in Nature Neuroscience on October 12, 2026.
## FAM193B Expression Impact
More CCG repeats increased FAM193B expression, leading to nerve cell DNA damage and cellular harm.
## Enzyme Interaction
FAM193B protein interacts with enzymes GSK3alpha and GSK3beta, linked to Alzheimer’s proteins.
## Clinical Applications
The finding could improve Alzheimer’s risk prediction in clinical settings with ancestral-specific considerations.
## Need for Further Research
Larger studies and functional research are needed to confirm the gene’s role in Alzheimer’s disease.
## Key takeaway

A DNA sequence repeat in the FAM193B gene doubles Alzheimer’s odds for those with 18+ repeats compared to 11 or fewer.
