BEIJING : Chinese researchers reported that they have analysed genetic features of familial Alzheimer's Disease in China, to detect the distribution of a gene mutation among Chinese FAD patients.
When more than two people in a family have Alzheimer's disease , it is categorised as a FAD. About 25 per cent of all Alzheimer's diseases is familial. Researchers from Capital Medical University in Beijing reported in the journal Alzheimer's & Dementia that they built the Chinese Familial Alzheimer's Disease Network in 2002 to collect FAD cases.Previous studies have found that mutations in the amyloid protein precursor , presenilin-1 and presenilin-2 genes are a known cause of FAD.
Researchers said that they found 50 variants of PSENs/APP mutations, 11 of which were reported for the first time.The researchers said that the low mutations rate of PSENs/APP indicates that Chinese FAD patients have different genetic features from other ethnic groups, and further research is needed.
In the future, gene editing may be applied to fix genetic defects and hold potential to treat FAD, they said. - Xinhua
