On examination of muscle biopsy material, the nuclear material is located predominantly in the center of the muscle cells, and is described as having any "myotubular" or<unk> " appearance. In terms of describing the muscle biopsy itself, "myotubular" or<unk> ” are almost synonymous, and both terms point to the similar cellular-appearance among MTM and<unk> . Thus, pathologists and treating physicians use those terms almost interchangeably, although researchers and clinicians are increasingly distinguishing between those phrases. In general, a clinical<unk>  and a muscle biopsy showing a<unk>  (nucleus in the center of the muscle cell) appearance would indicate a<unk>  <unk> . The most commonly diagnosed<unk>  is myotubular<unk>  (MTM). However, muscle biopsy analysis alone cannot reliably distinguish myotubular<unk>  from other forms of<unk> es, and thus genetic testing is required.Diagnostic workup is often coordinated by a treating neurologist. In the United States, care is often coordinated through clinics affiliated with the Muscular Dystrophy Association.
