Summaries for Cap Myopathy

Genetics Home Reference : 25 Cap myopathy is a disorder that primarily affects skeletal muscles, which are muscles that the body uses for movement. People with cap myopathy have muscle weakness (myopathy) and poor muscle tone (hypotonia) throughout the body, but they are most severely affected in the muscles of the face, neck, and limbs. The muscle weakness, which begins at birth or during childhood, can worsen over time. Affected individuals may have feeding and swallowing difficulties in infancy. They typically have delayed development of motor skills such as sitting, crawling, standing, and walking. They may fall frequently, tire easily, and have difficulty running, climbing stairs, or jumping. In some cases, the muscles used for breathing are affected, and life-threatening breathing difficulties can occur. People with cap myopathy may have a high arch in the roof of the mouth (high-arched palate), severely drooping eyelids (ptosis), and a long face. Some affected individuals develop an abnormally curved lower back (lordosis) or a spine that curves to the side (scoliosis). The name cap myopathy comes from characteristic abnormal cap-like structures that can be seen in muscle cells when muscle tissue is viewed under a microscope. The severity of cap myopathy is related to the percentage of muscle cells that have these caps. Individuals in whom 70 to 75 percent of muscle cells have caps typically have severe breathing problems and may not survive childhood, while those in whom 10 to 30 percent of muscle cells have caps have milder symptoms and can live into adulthood.

MalaCards based summary : Cap Myopathy, also known as cap disease, is related to myopathy, congenital and myopathy, congenital, with fiber-type disproportion. An important gene associated with Cap Myopathy is TPM3 (Tropomyosin 3), and among its related pathways/superpathways are Cardiac muscle contraction and cGMP-PKG signaling pathway. The drugs Anti-Bacterial Agents and Antibiotics, Antitubercular have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle and prostate, and related phenotypes are high palate and reduced tendon reflexes

NIH Rare Diseases : 52 Cap myopathy is a disorder that primarily affects skeletal muscles, the muscles that the body uses for movement.

Individuals in whom 70 to 75 percent of muscle cells have caps typically have severe breathing problems and may not survive childhood, while those in whom 10 to 30 percent of muscle cells have caps have milder symptoms and can live into adulthood. Cap myopathy can be caused by mutations in the in the ACTA1 , TPM2 , or TPM3 genes . This condition follows an autosomal dominant manner of inheritance, however, most cases are not inherited ; they result from new mutations in the gene and occur in people with no history of the disorder in their family.

KEGG : 36 Cap myopathy is a rare congenital myopathy morphologically characterized by the presence of cap-like structures which are sharply demarcated structures of disorganized thin filaments in the periphery of muscle fibers. These structures are in fact disarranged myofibrils with enlarged Z discs and no thick filaments. The severity of the disease is related to the number of fibers affected. Therefore, patients may present with a neonatal fatal form or have a more stable course of the disease in the infant non-fatal form. Respiratory problems are common. All the currently recognized genes associated with cap myopathy (TPM2, TPM3 and now ACTA1) encode components of the sarcomeric thin filaments.
