Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy. Pseudopolycoria is often associated with Seckel syndrome, posterior polymorphous dystrophy, and juvenile glaucoma. These mice exhibited a syndrome similar to early-onset human muscular dystrophy. Antisense-oligonucleotide mediated exon skipping is another possibility for Duchenne muscular dystrophy. Those could be&colon; dystrophy, myopathy and mitochondrial disorders. Lisch epithelial corneal dystrophy is associated with Xp22.3. CPRA is also known as retinal pigment epithelial dystrophy (RPED). Further research into myostatin and the myostatin gene may lead to therapies for muscular dystrophy. Cathepsin A increased in muscles moderately affected by muscular dystrophy and denervating diseases. Joining Jack being a charity dedicated to the needs of sufferers of Duchenne muscular dystrophy. The incidence of congenital myotonic dystrophy is thought to be about 1&colon;20,000. Constipation is also common in individuals with muscular and myotonic dystrophy. Specific muscle groups are affected by different types of muscular dystrophy. The cardiac problems that occur with EDMD and myotonic muscular dystrophy may require a pacemaker. The trapezius muscle is one of the commonly affected muscles in facioscapulohumeral muscular dystrophy (FSHD).
