The Mayo Clinic announced Friday that it is investigating the possibility that a genetic mutation could cause male hair loss in some people.
The mutation is found in the DNA of male mice, and is thought to occur in the same gene.
The discovery of the mutation comes after a geneticist found that about 20 percent of male hair in men is lost in the course of a year.
The Mayo study is the latest to suggest that the loss of hair in males is due to a genetic change in the gene that makes the hair grow.
The gene that causes the mutation has not been identified, but geneticists have speculated it may cause hair loss because it causes mutations that make cells less efficient.
Researchers are trying to figure out whether that’s true.
If it is, the gene could be used to predict who will have hair loss.
Researchers also hope to find out more about the genetic factors that cause hair growth.
It’s not known how common the mutation is, but there are cases of it occurring in people in Europe and Australia.
The study was published in the journal Molecular Biology and Evolution.
