Citando:
"The researchers then analyzed participants' genomes, looking for genetic variations, known as single-nucleotide polymorphisms, or SNPs, that were linked with severe hair loss. That search revealed 287 genetic variations, located on more than 100 genes, that were linked with severe hair loss.
Many of the genetic variations were located on or near genes that have previously been linked with hair growth, hair graying or the biological structures involved in making hair, the researchers said.
Forty of the genetic variations were located on the X chromosome, which men inherit from their mothers, the researchers said. One of the genes on the X chromosome — the gene for the androgen receptor, which binds to the hormone testosterone — was strongly linked with severe hair loss. Previous studies have also pinpointed this gene as tied to male pattern baldness.
The researchers then created a formula, which resulted in a genetic "risk score," to try to predict the chances of severe hair loss in the men."
