Miyoshi myopathy

Miyoshi myopathy is a type of muscle condition that mainly affects the muscles in the lower legs, particularly the calf muscles such as the gastrocnemius and soleus. People with this condition may notice weakness in these muscles, which can make it challenging to stand on tiptoes. This condition is classified as a distal myopathy because it affects the muscles farthest from the center of the body. The information provided is based on its definition and known characteristics. Further details about the overall impact or progression are limited in the current sources.

The most common symptom of Miyoshi myopathy includes weakness in the muscles of the lower leg. People with this condition often have difficulty standing on tiptoes due to weakness in the distal lower extremity, specifically in the muscles located in the posterior compartment of the lower leg.

Miyoshi myopathy is understood to be a genetic muscle condition. It is described as having an autosomal recessive inheritance pattern, which means that the condition is typically passed down when both parents carry a gene change. Detailed genetic causes or specific gene mutations are not provided in the available information.
