The DNA project is part of the National Health & Medicine Big Data (Nanjing) Center, a six-billion yuan (about USD one billion) project, Lan Qing, Deputy Director of the provincial Health and Family Planning Commission said.
During the first phase, health and medical information on about 80 million people, the equivalent of the population in Jiangsu, will be stored at the center, Lan said.
"When the facilities are ready, the designed capacity for DNA sequencing will be up to 400,000 to 500,000 samples per year," state-run Xinhua news agency reported.
Researchers will then use big data created in the database to study genetic mutations related to major diseases, look for the impact of interaction between genes and environmental concerns on human heath, and provide statistical support for diagnosis and treatment of major diseases, Lan said.
Cai Long, board director of Yangzi Group, said the programme will focus on population genetics, newborns, childhood brain and cognitive development, cancer, and rare and chronic diseases.
The database is expected to be complete in around four years, he said.
