Abstract:
Dysferlinopathies exhibit marked heterogeneity in the initial distribution of muscle involvement at the onset of the disease. We describe a Japanese patient with dysferlinopathy who exhibited distal anterior compartment myopathy (DACM) with early contractures of the ankle, whose pedigree included patients with two other types of dysferlinopathy. The existence of three phenotypes of dysferlinopathy in one pedigree is reported, indicating the involvement of molecules other than dysferlin in the pathogenesis.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
