Duchenne muscular dystrophy (DMD) is a progressive muscular damage disorder caused by mutations in dystrophin gene. Cardiomyopathy may first be evident after 10 years of age and increases in incidence with age. We present a boy diagnosed at 18 months with a rare phenotype of DMD in association with early-onset hypertrophic cardiomyopathy (HCM). The cause of DMD is a deletion of exons 51-54 of dystrophin gene. The cause of HCM was verified by whole exome sequencing. Novel missense variations in two genes: Show less
