Myosinopathies
WebHere, actinopathies and myosinopathies often occur early in childhood while catabolic PAMs are largely of adult or even late onset. The common principle of these PAMs is that immunohistochemical identification of certain proteins resulted in subsequent molecular analysis of respective genes, identification of mutations, and demonstration of ... WebMyosinopathy: (E) Muscle fibers display very light opaque areas, the hyaline bodies, sharply demarcated from darker, greenish sarcomeric regions, modified Gomori's trichrome stain. (F) The hyaline bodies are devoid of oxidative enzyme histochemical activity, menadione-linked α-glycerophosphate dehydrogenase.
