2003: Premature Aging Gene Identified

A team of researchers led by the National Human Genome Research Institute announced the discovery of a gene associated with a rare genetic disease that leads to premature aging. Hutchinson-Gilford progeria syndrome (HGPS), commonly called progeria, affects one in 8 million live births worldwide. The disorder has no diagnostic test or treatment. Children with the disease appear to age at a rate 5 to 10 times faster than normal.

Researchers found that the most common cause of progeria is a single base substitution in a gene located on chromosome 1. Now that the causative gene has been identified, a DNA-based test for progeria is available at five clinical laboratories [genetests.org]. This allows doctors to diagnose or rule out progeria in newborns much earlier than waiting for visible symptoms to appear.
