Most genetic tests that offer health information should not be sold directly to the public, the UK's human genetics watchdog recommended last week. In a new report entitled 'Genes direct: ensuring the effective oversight of genetic tests supplied directly to the public', the Human Genetics Commission (HGC) called for stricter controls on predictive genetic tests, but not an outright ban.
The HGC based its report on the findings of a consultation on the sale of so-called 'over the counter' genetic tests, which are becoming increasingly available. Some tests, such as those produced by UK firm Sciona, offer general health advice, but others claim to predict a person's risk of diseases such as cancer. Baroness Helena Kennedy QC, who chairs the commission, said that the majority of genetic tests should be carried out under the supervision of a doctor, and that 'people need to think twice before paying money for something they may not need or understand'.
The report recommends that controls are required to ensure that companies market high quality tests with good customer support, and that kits relying on home testing or sampling should be discouraged. It suggested that a number of bodies could regulate such genetic tests, including the Medicines and Healthcare Products Regulatory Agency (MHRA), the proposed new Human Tissue Authority, and the UK Genetic Testing Network. It also called for a consumer awareness campaign, to help people decide which tests are suitable for them. 'Predictive genetic tests performed without a medical consultation may provide false reassurance or cause unnecessary alarm to people' said Philip Webb, chairman of the group that produced the report.
