Involvement in diseaseⁱ

Emery-Dreifuss muscular dystrophy 6, X-linked (EDMD6)2 Publications

The disease is caused by variants affecting distinct genetic loci, including the gene represented in this entry.

Disease descriptionA form of Emery-Dreifuss muscular dystrophy, a degenerative myopathy characterized by weakness and atrophy of muscle without involvement of the nervous system, early contractures of the elbows, Achilles tendons and spine, and cardiomyopathy associated with cardiac conduction defects.

Scapuloperoneal myopathy, X-linked dominant (SPM)2 Publications

The disease is caused by variants affecting the gene represented in this entry.

Disease descriptionA disease characterized by progressive muscle weakness and wasting, upper and lower limbs weakness, foot drop, scapular winging, and myopathic changes on muscle biopsy. Most affected individuals become wheelchair-bound.

Myopathy, X-linked, with postural muscle atrophy (XMPMA)2 Publications

The disease is caused by variants affecting the gene represented in this entry.

Disease descriptionA progressive muscular dystrophy with onset in adulthood. Affected individuals develop a proximal myopathy characterized by specific atrophy of postural muscles, limited neck flexion, bent spine, contractures of the Achilles tendon, respiratory problems, and cardiomyopathy. Patients may show muscle hypertrophy in the early stages of the disorder.

Reducing body myopathy, X-linked 1A, severe, with infantile or early childhood onset (RBMX1A)3 Publications

The disease is caused by variants affecting the gene represented in this entry.

Disease descriptionA rare myopathy clinically characterized by rapidly progressive muscular weakness, and pathologically by the presence of intracytoplasmic inclusion bodies strongly stained by menadione-linked alpha-glycerophosphate dehydrogenase in the absence of substrate, alpha-glycerophosphate. The term 'reducing body' refers to the reducing activity of the inclusions to nitroblue tetrazolium in the absence of substrate. This condition is also commonly associated with rimmed vacuoles and cytoplasmic bodies. Death in childhood is frequent in the severe form of the disease, due to respiratory failure.
