Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy. The symptom of muscle weakness usually begins around the age of four in boys . Fukuyama type muscular dystrophy (FCMD) is a congenital progressive muscular dystrophy characterized by brain malformation (cobblestone lissencephaly).

The CMDIR is a patient self-report registry with the goal to register the global congenital muscle dlstrofia population including persons with congenital myopathy, congenital muscular dystrophy, and congenital myasthenic syndrome.

Punctate hemorrhages were seen in the parenchyma, and ventriculitis was identified. The involvement of multiple sibs of both sexes and parental consanguinity reported by Fukuyama et al. How to cite this article. This region spans part of the 3-prime end of the fukutin coding region, a proximal part of the 3-prime UTR, and the SVA insertion. At autopsy, the medial aspect of the brain showed an interhemispheric cyst, incomplete cleavage of the thalamus and corpora quadrigemina, an absent corpus callosum, and rhombencephalic hypoplasia.

Phenotypic Expression In Muscular Dhystrophy. Localization of laminin subunits in the central nervous system in Fukuyama congenital muscular dystrophy: The medication ataluren have been approved for certain cases in Europe. Calf muscle enlargement pseudohypertrophy is quite obvious. The vast majority of affected individuals have at least one copy of the same mild FKTN variant, c.

Yoshioka and Kuroki performed clinical and genetic studies in 41 families with FCMD in Japan in an attempt to distinguish it from the Walker-Warburg syndrome and muscle-eye-brain disease, both of which, like FCMD, show an association of type II lissencephaly and ocular anomalies. FCMD is characterized clinically by a peak motor function that, at best, usually allows patients to sit unassisted or slide on the buttocks.

Postmortem examination revealed severe malformations of the central nervous system, including agyria and cortical disorganization, and congenital muscular dystrophy.

The most common direct cause of death in people with DMD is respiratory failure. Progressive cardiac involvement, and swallowing and feeding disturbances leading to recurrent aspiration pneumonia and death occur in infants with severe FCMD and in patients over ten years of age.

People with Becker’s distrpfia dystrophywhich is milder than DMD, have a form of dystrophin which is functional even though it is shorter than normal dystrophin.

Diagnostic approach to the congenital muscular dystrophies. Kobayashi et al [] suggested that fukutin is located in the extracellular matrix, where it interacts with and reinforces a large complex encompassing the outside and inside of muscle membranes.
