WEDNESDAY, Feb. 15 (HealthDay News) -- Researchers report that they've discovered the importance of a particular gene in kicking off puberty in humans, a finding that offers insight into how the mysterious process begins and could help children who suffer from a rare disease that prevents the start of puberty.

An analysis of the DNA of a family whose members have suffered from the disease confirmed that the gene is vital because it paves the way for the body to process a hormone known as kisspeptin.
