Cheaper, faster, more accurate test to identify gene defects in heart patients

A new technique could eventually enable doctors to diagnose genetic heart diseases by rapidly scanning more than 85 genes known to cause cardiac anomalies. Researchers say that the gold standard of genome sequencing involves thousands of genes, costs $1,000 or more and can take weeks or months to get results. For a patient with a heart condition that's difficult to diagnose, it makes no sense to sequence the entire 22,000-gene genome, since fewer than 200 genes are known to affect the heart, the...
