China Uses DNA to Track Its People, With the Help of American Expertise – The New York Times

“Dr. Budowle and his team abhor the use of DNA technology to persecute ethnic or religious groups,” Mr. Carlton said in the statement. “Their work focuses on criminal investigations and combating human trafficking to serve humanity.”

Dr. Kidd’s data became part of China’s DNA drive.

In 2014, ministry researchers published a paper describing a way for scientists to tell one ethnic group from another. It cited, as an example, the ability to distinguish Uighurs from Indians. The authors said they used 40 DNA samples taken from Uighurs in China and samples from other ethnic groups from Dr. Kidd’s Yale lab.

In patent applications filed in China in 2013 and 2017, ministry researchers described ways to sort people by ethnicity by screening their genetic makeup. They took genetic material from Uighurs and compared it with DNA from other ethnic groups. In the 2017 filing, researchers explained that their system would help in “inferring the geographical origin from the DNA of suspects at crime scenes.”

For outside comparisons, they used DNA samples provided by Dr. Kidd’s lab, the 2017 filing said. They also used samples from the 1000 Genomes Project, a public catalog of genes from around the world.

Paul Flicek, member of the steering committee of the 1000 Genomes Project, said that its data was unrestricted and that “there is no obvious problem” if it was being used as a way to determine where a DNA sample came from.

The data flow also went the other way.

Chinese government researchers contributed the data of 2,143 Uighurs to the Allele Frequency Database, an online search platform run by Dr. Kidd that was partly funded by the United States Department of Justice until last year. The database, known as Alfred, contains DNA data from more than 700 populations around the world.

This sharing of data could violate scientific norms of informed consent because it is not clear whether the Uighurs volunteered their DNA samples to the Chinese authorities, said Arthur Caplan, the founding head of the division of medical ethics at New York University’s School of Medicine. He said that “no one should be in a database without express consent.”
