"Using gene sequencing tools, scientists from Johns Hopkins Medicine and the University of British Columbia have found a set of genetic mutations in samples from 24 women with benign endometriosis, a painful disorder marked by the growth of uterine tissue outside of the womb. The findings, described in the May 11 issue of the New England Journal of Medicine, may eventually help scientists develop molecular tests to distinguish between aggressive and clinically "indolent," or non-aggressive, types of endometriosis.
"Our discovery of these mutations is a first step in developing a genetics-based system for classifying endometriosis so that clinicians can sort out which forms of the disorder may need more aggressive treatment and which may not," says Ie-Ming Shih, M.D., Ph.D., the Richard W. TeLinde Distinguished Professor in the Department of Gynecology & Obstetrics at the Johns Hopkins University School of Medicine and co-director of the Breast and Ovarian Cancer Program at the Johns Hopkins Kimmel Cancer Center.
Endometriosis occurs when tissue lining the uterus forms and grows outside of the organ, most often into the abdomen. The disease occurs in up to 10 percent of women before menopause and half of those with abdominal pain and infertility problems. In the 1920s, Johns Hopkins graduate and trained gynecologist John Sampson first coined the term "endometriosis" and proposed the idea that endometriosis resulted when normal endometrial tissue spilled out through the fallopian tubes into the abdominal cavity during menstruation..."
