MedicalResearch.com Interview with: Joyce Y Tung Ph.D. Research Team 23andMe Inc. Mountain View, California, USA MedicalResearch.com: What are the main findings of the study? Dr. Tung: 23andMe researchers identified four genetic markers that were significantly associated with the development of stretch marks, including one near the elastin (ELN) gene. This finding may further explain why some individuals are more susceptible to the skin condition. Given that loose skin is a symptom of syndromes caused by deletion or loss-of-function mutations in ELN, these results also support the hypothesis that variations in the elastic fiber component of the skin extracellular matrix contribute to the development of stretch marks.
