Alpha-actinopathy
MONDO:0100084A musculoskeletal system disorder that covers a wide spectrum of phenotypes and is caused by pathogenic variants in the skeletal muscle α-actin gene (ACTA1). These variants lead to a variety of overlapping adult onset and congenital myopathies characterized by muscle weakness, hypotonia, myopathic face, respiratory dysfunction, and rarely cardiac involvement. Specific skeletal muscle structural lesions visible on muscle biopsy include actin accumulations, nemaline and intranuclear bodies, fiber-type disproportion, cores, caps, dystrophic features and zebra bodies. Disorders associated with ACTA1 pathogenic variants can have autosomal dominant (90%) or recessive (10%) inheritance.
Also known as: actin myopathy, actinopathy, ACTA1 disease, alpha actinopathy, alpha-actinopathy

New handheld scanner could replace MRI for muscle disease monitoring
Diagnosis Recruiting nowThis study is testing a handheld device called mScan that uses a tiny, painless electrical current to measure muscle health. Researchers want to see if it can give similar results to an MRI, but faster and more conveniently. The study involves 150 adults with and without muscle d…

Simple blood test may predict muscle disease severity
Knowledge-focused Recruiting nowThis study is looking at whether a molecule in the blood called miR-1 can help doctors understand how muscle diseases like Duchenne muscular dystrophy and myotonic dystrophy are progressing. Researchers will compare miR-1 levels in 104 people, including patients with different mu…
