Preventive genomics has arrived

Our expert voices conversation on genetic testing for cancer.

Genetic testing used to be very expensive, and so was done infrequently and judiciously. But advances in DNA sequencing technology now let us evaluate hundreds of genes for a fraction of what it used to cost to sequence just one.

The American College of Medical Genetics and Genomics has identified a list of genes associated with preventable adult-onset cancer syndromes. Each of these conditions has well-established, evidence-based guidelines for creating surveillance and treatment plans that your physician can use to guide preventive management.

Bottom line: We've long known that 5-10% of cancers derive from DNA mutations we inherit. These cancers tend to occur at an earlier age and affect multiple organs. If we could look at everyone's DNA, we would know who is silently carrying one of these misspellings and take steps to prevent them from developing the disease.

World coronavirus updates

Over 500 schools in South Korea have either closed or postponed reopening, according to the Korea Times, which cites data from the Ministry of Education.

Why it matters: South Korea has been a model for how to handle the novel coronavirus, and the closures reportedly followed concerns from parents and teachers over child safety. The country's confirmed death toll has plateaued at 269 over the past few days, with few increases, per Johns Hopkins data.

Trump to end Hong Kong’s special trade status

President Trump announced on Friday that the U.S. would be fundamentally changing longstanding policies toward Hong Kong as a result of Chinese encroachment on the city's autonomy.

Why it matters: Trump said he would be effectively ending the special trade status that has allowed Hong Kong to flourish as a gateway to the Chinese market. That leaves an uncertain future for businesses that operate in Hong Kong, not to mention the city's 7 million residents, and could be met with reprisals from Beijing.
