Gene Causing Grey Hair Could Be Switched Off
The gene responsible for causing grey hair could be switched off, scientists say according to a report by Reuters.
A newly discovered gene, IRF4, has been identified by scientists as being responsible for graying hair. The discovery was the result of more than 6,000 DNA samples collected in Latin America. The country was chosen for the diverse ancestry of those who live there, according to the Reuters report. The scientific study also found that grey hair is much more likely for those with European ancestry.
“This genetic variant of IRF4 has two forms,” Dr. Kaustubh Adhikari of University College London was quoted as saying. “One form is present worldwide, and the other form is present only in Europeans. We saw that this particular European specific form gives you almost double chance of having hair grey.”
IRF4 plays a role in regulating melanin in the human body, which is responsible for determining hair color. Age and environment also impacts how quickly IRF4 initiates the process of hair turning grey. Scientists investigating the gene say that its identification could lead to treatment to stop hair graying entirely.
“Switching off a gene is of course feasible,” Professor Andres Ruiz-Linares of University College London was quoted as saying. “The issue is whether it will have the desired effect and whether it’s the right thing to do. In terms of trying to develop a therapy to delay or prevent hair graying, that is something that is potentially feasible.”
Nevertheless, scientists believe that developing a cosmetic treatment for switching off the gene could take years of research.
