DAG1 and muscular dystrophy: Several muscular dystrophy mutant strains of zebrafish have been identified including those with mutations in dystrophin (sapje), laminin α2 (candyfloss), and dystroglycan (pachytail and dag1hu3072) (Bassett et al., 2003; Hall et al., 2007; Gupta et al., 2011) while several other genes causing muscular dystrophy have been disrupted by antisense morpholino approaches [reviewed in Gibbs et al. (2013a)].
