Can You Inherit Stretch Marks?

By    |   Friday, 23 Aug 2013 01:28 PM

Pregnancy and weight gain aren't the only cause of stretch marks. New research has linked genetic factors to the condition — known medically as striae distensae — that indicates it may be hereditary.

Researchers at the personal genetics company 23andMe identified four genetic markers associated with the development of stretch marks that indicate why some individuals are more susceptible to the skin condition — findings they say could lead to better treatments.

The 23andMe researchers based their conclusions on an analysis of 33,930 unrelated 23andMe customers, including nearly 14,000 people with stretch marks and more than 20,000 without.
 
"To date, no genetic variants were known to be associated with isolated stretch marks that affect the general public," said lead researcher Joyce Tung, 23andMe director of research.

"Through this first of its kind study, we've identified new genetic associations that can provide deeper insights into the root causes of stretch marks, and look forward to continuing research in this space.
 
"One intriguing area for further study is the potential effect of genes associated with obesity on the development of stretch marks, both independent of and via changes in BMI."
 
Stretch marks strike between 50 percent and 80 percent of adult men and women, but the exact causes are unknown. Many factors are thought to play a role, including excessive skin distension from pregnancy, growth spurts, and weight gain.
 
Popular treatments include creams and laser removal that aim to stimulate collagen production to decrease the appearance of stretch marks. But the new research may point the way to improved methods to prevent and treat stretch marks, Tung said.
