DNA screening of 4,200 Alabamians warns them, helps science

[2019.11.08, Fri 00:03] An Alabama genetic research institute said today it has screened the DNA of 4,200 Alabama men and women for cancer risk and found it in about 150 people or 3 percent. More than half of that 150 have no strong family history of cancer, researchers at the HudsonAlpha Institute of Biotechnology in Huntsville said today at the institute's annual "Tie the Ribbons" lunch supporting breast and ovarian cancer research. The test was developed by genetic testing company Kailos Genetics and screens for the well-known BRCA1 and BRCA2 genes plus several others linked to breast, ovarian, colon and other cancers. Researcher Sara Cooper said the lack of family history in positive test subjects "Is why this initiative is so important." Testing can fill the gaps in family history with facts, she said. Cooper said genetic testing can also reveal risk of other medical issues beyond cancer, including cardiovascular disease. There are genes researchers haven't found that contribute to cancer risk. There are new DNA changes discovered in genes already associated with cancer.
