Gene discovery by Canadian researcher ‘major breakthrough’ in HIV research: PHAC
Global News
PHAC researchers and partners found the genetic variants that impact a human gene called CHD1L, which restricts HIV replication. It's a major breakthrough in HIV research.
A specific gene may explain why some people have naturally lower viral loads of HIV, which slows down the virus from replicating and transmitting, according to research from the Public Health Agency of Canada (PHAC).
Published Wednesday in Nature, PHAC researchers along with international partners, found the genetic variants that impact a human gene called CHD1L, which restricts HIV replication.
“This is the first new genetic variant discovered in nearly 30 years of HIV research. It is a major breakthrough in our understanding of the virus and may lead to new HIV treatment and prevention strategies,” PHAC stated in a release.
In order to find this gene, the researchers examined the genetics of close to 4,000 people around the world living with HIV who are of African ancestries — a key population that is disproportionately affected by HIV — and provided informed consent to study how their genetic background influenced their response to the virus.
The scientists found CHD1L and believe this gene has a role to play in limiting viral replication. This means that the virus is unable to replicate as quickly or efficiently in people who carry specific genetic variants compared to others who do not.
More research is required to fully understand exactly how this gene is limiting viral replication, the researchers stated.
“This important discovery will help scientists target their efforts to discover new medical interventions for HIV, PHAC stated. “It can pave the way for the development of new prevention and treatment strategies.”
