At the first clinical examination, all patients were able to walk without support and presently nine became wheelchair-bound and three needed walking assistance (mean time to loss of autonomous walk of 17 ±9 years). [ap1-dev.uc.pt]

Abstract We present an overview of autosomal recessive distal muscular dystrophy (ARDMD), including recent molecular genetic findings. ARDMD is often referred to as Miyoshi-type distal muscular dystrophy (MDMD) or Miyoshi myopathy (MM). [pubmed.ncbi.nlm.nih.gov]

The tendon reflexes were present and symmetric. The CK was 2850U/l, aldalose 273U/l, LDH 747U/l. The EMG showed a myopathic pattern. [scielo.br]

  Miyoshi and col and Barohn8,11 reported high level of this enzyme in asymptomatic patients' relatives. Probably they were pre-clinical individuals or were heterozigotics. [scielo.br]

  There is a slowly progressive weakness and the proximal muscles may be involved lately3,6,7. The CK is usually high1,3-6. [scielo.br]

• Myalgia

  Exercise-induced myalgia and aching discomfort in the calves can be an early symptom. Anterior compartment muscles of the distal lower extremities eventually become weak as well. [orpha.net]

Management and treatment No definitive treatments for MM exist and management is mainly supportive. [orpha.net]

There is currently no cure or definitive treatment for Miyoshi myopathy. [rarediseases.info.nih.gov]

The technique would permits a less invasive, faster and cheaper diagnosis and allows to quantify dysferlin levels when new treatments would be tested9. The high levels of CK in MM is due to great muscular lesion. [scielo.br]

Prognosis Progression is variable with some patients remaining fairly stable with distal weakness, while others can have a more aggressive pattern involving both proximal and distal muscles. [orpha.net]

Etiology MM is caused by mutations in the DYSF gene (2p13), which encodes dysferlin. The latter orchestrates skeletal muscle membrane repair and has also been associated with myogenesis, angiogenesis and microtubule dynamics. [orpha.net]

Summary Epidemiology Miyoshi myopathy (MM) is the most common form of recessive distal myopathy in populations with founder mutations such as Libyan and Israeli Jewish population, Italian and Spanish populations. [orpha.net]

Management depend on the specific signs and symptoms, and is aimed to prolong survival and improve quality of life:.[1] Physical therapy and stretching exercises to promote mobility and prevent contractures Use of mechanical aids such as canes, walkers [rarediseases.info.nih.gov]
