Scientists studying a Colombian family with a devastating inherited form of Alzheimer’s have discovered a genetic oddity that appears to delay the onset of symptoms by five years.
The reason for her resilience was a rare genetic variation. She had two copies of an unusual gene called APOE3. This gene had a specific mutation known as Christchurch. This rare genetic setup appeared to protect against Alzheimer’s, significantly delaying its start. Dr. Eliezer Masliah of the National Institute on Aging noted, “It gives you a lot of comfort that modifying one of the copies could be really helpful,” at least in delaying the disease’s progression.
