Excerpt from article:
"Dr Anna Middleton, vice-chair of the Association of Genetic Nurses and Counsellors, frequently encounters worried patients. 'While it's fantastic to make testing more accessible, companies don't often offer a pathway to discuss results,' she says. This leaves the NHS to pick up the pieces. 'One patient's home DNA test said she was carrying the BRCA1 gene and other test companies confirmed it,' says Dr Middleton. 'Distraught, she insisted on NHS genetic services, believing she'd need a mastectomy and her ovaries removed. But when tested again, they found the companies had made a mistake.'...'There are companies whose business midel isn't the cost of the test. What they want is your valuable DNA raw data, which they will sell. If they do sell your personal profile, your 3 billion bits of DNA will be in the hands of a commercial company.'"
