Until recently it has not been technically and financially possible to offer routine genetic diagnostics due to large number of disease related genes and an unknown number of unidentified DCM associated genes at this point. Fortunately there has been a revolutionary development in DNA sequencing technology through the last couple of years making it possible to examine an almost unlimited amount of genes in large patient cohorts fast and to an acceptable expense. The Technology is called "Next Generation Sequencing" (NGS), and it can also be used to discover new disease associated genes and do genetic association studies.
