It May be All in Your Genes

People may inherit a genetic predisposition to rotator cuff injury, according to a study presented Thursday at the American Academy of Orthopaedic Surgeons meeting in Las Vegas, which found that rotator cuff injury seems to run in families.
Heredity is likely to “play a strong role in determining whether people are at risk for the development of a rotator cuff tear,” study chief Dr. Robert Zaray Tashijian, University of Utah School of Medicine, Salt Lake City, told Reuters Health. “Consequently, individuals may use this information in implementing a preventative program.”
According to Tashijian, only one previous study looked at the heredity component of rotator cuff problems. That study, however, only looked at first degree relatives (such as mothers, sisters or brothers) and thus the findings may have been confounded by environmental factors.
“In order to strongly suggest a genetic predisposition, you need to show an increased relative risk out to third degree relatives,” he explained. “We have actually determined an increased risk out to third cousins — well beyond third degree relatives.”
