The Human Genome Project described the first (almost) complete reference genome, but it didn鈥檛 say much about human variation. For that, scientists had to conduct massive population genomics (pop gen) studies, sequencing millions of people to better understand the genetic distinctions, in specific populations, that confer good health or disease. The UK Biobank, deCODE, and the Million Veterans Program were early examples.

These programs have produced incredibly useful genomic data, but they have also left significant gaps. In many cases, pop gen studies have been heavily Eurocentric, missing data that could help scientists, clinicians, and public health officials understand the genomic variations that affect people of African, South American, or Asian descent.

鈥淭he vast majority of genomic data that scientists have collected is from people of European descent,鈥� says Helen Speirs, VR真人彩票鈥檚 leader for Large National Genomics Initiatives in Africa, the Middle East, and Asia (AMEA). 鈥淭hat means we can鈥檛 make a lot of calls about how genomic variants in people with non-European ancestry cause disease or how to develop drugs that will be most effective for them.鈥�

To help close these gaps, dozens of nations have begun pop gen programs. In time, these efforts will help them gather nuanced molecular information to drive better care for their people鈥� precision genomics.

鈥淭hese national initiatives all want to utilize genomics in health care in some form,鈥� says Graeme Bethel, VR真人彩票鈥檚 head of Strategic Growth for AMEA. 鈥淏ut first, they must sequence thousands of research genomes to get a better understanding of their population and develop the infrastructure needed to scale genomics into health care.鈥�

Building a pop gen program from the ground up

Having supported the UK Biobank and other programs from their earliest days, VR真人彩票 has a unique position in the pop gen ecosystem. Quite often, company experts step in as consultants to help these long and complex projects get off the ground.

鈥淲e try to engage very early in these projects to help them avoid the mistakes of the past,鈥� Bethel says. 鈥淭here are government, institutional, scientific, and clinical people involved, and they all want to understand how these complicated collaborations are going to work.鈥�

While many emerging nations want to initiate pop gen projects, they may lack the molecular biology infrastructure to build robust efforts. Underdeveloped sequencing programs and cold storage capabilities are just two potential barriers.

鈥淭hey understand they have to move these projects forward, or they鈥檙e going to fall further behind,鈥� says Speirs, 鈥渂ut the challenges can be huge. Even the basics of recruiting and maintaining a workforce can be quite difficult.鈥�

Some countries have overcome these problems by shipping samples abroad for sequencing. The new push is to maintain data ownership to ensure that the people providing their DNA receive the full benefits of sequencing.

Clinical and economic payoffs

In addition to producing scientific and clinical knowledge, these efforts can be engines for economic development. Japan鈥檚 ToMMo project grew out of recovery efforts following the 2011 earthquake and tsunami near Fukushima.

Worldwide, the number of pop gen projects is expanding rapidly, counting efforts in Thailand, Saudi Arabia, the United Arab Emirates, Australia, Singapore, Turkey, Nigeria, and other nations. In addition to gaining the unique insights only sequencing can provide, these countries hope to recruit investors and develop homegrown genomics industries.

These emerging biotech clusters generate well-paying jobs and attract talent from around the world. In some cases, scientists who emigrate to the US, UK, or other developed nations return to their home countries as the new industry creates an economic center of gravity.

Pharma companies and venture capitalists are also showing interest. Sequencing more diverse populations could uncover better drug targets (and produce better targeted drugs), which could benefit all populations.

鈥淚 was recently speaking to a private consortium in India that wants to invest in biobanks and generate sequencing and phenotypic data to really understand the Indian population,鈥� Bethel says. 鈥淐ompanies know that genomically informed drugs are less expensive to develop and more than twice as likely to get to market. It鈥檚 a powerful incentive.鈥� 鈼�
