Nebulin is normally expressed in nemaline myopathy.
Since the nebulin gene is located in the candidate gene locus of autosomal recessive nemaline myopathy, 2q21.2-q22, we examined five muscle biopsy specimens with monoclonal and polyclonal antibodies against nebulin in combination with the modified Gomori trichrome stain. We were able to demonstrate immunohistochemically that there was no abnormality in nebulin in the muscle fibers both with and without nemaline bodies. Although the molecular weight of nebulin was normal, it was slightly reduced in amount on immunoblotting.
