NEW YORK (Reuters Health) - Researchers in Germany have found that variations in a gene related to male sex hormones may be at the root of male-pattern baldness, the most common form of hair loss. The culprit is the androgen receptor gene, and it dwells on the X chromosome, which all men inherit from their mothers.

Experts have long believed that hair loss in inherited. But the new research, to be published in the American Journal of Human Genetics, is the first to identify a specific gene that may be involved, according to the study authors.

Other, yet-unidentified genes are likely involved in male-pattern baldness, possibly including ones handed down by fathers. But the new findings highlight the importance of mom's side of the family when it comes to a man's hairline, according to the study authors, led by Dr. Markus M. Nothen of the University of Bonn.

The researchers say they are continuing to hunt down the other genes involved in early-onset male-pattern baldness. Scientists hope that getting at the genetic roots of hair loss will eventually spawn better baldness treatments or a cure.

A few more years and there may even be a cure
