Traditional genetic analysis is best suited to diagnose monogenic conditions, such as Duchenne muscular dystrophy (Duchenne MD), resulting from dystrophin mutations, or cystic fibrosis, which is caused by cystic fibrosis transmembrane conductance regulator (CFTR) mutations (Brewington and Clancy, 2016; Okubo et al., 2016). Here, CFTR is linked to Duchenne muscular dystrophy.
