Immunofluorescence staining. A NADH and H&E staining in the proband’s muscle tissue (10X). B Skin fibroblasts treatment with ascorbic acid. The proband’s cells (III:2) presented the absence of secreted protein and collagen VI network; collagen staining was observable only in the cell’s cytoplasm as in NT well (63X). In her mother (II:2) and in the asymptomatic brother (III:3), a collagen VI fine network was visible in the extracellular matrix
