  • a novel myh7 mutation links congenital fiber type disproportion and myosin storage myopathy
    Neuromuscular Disorders, 2011
    Co-Authors: Saida Ortolano, Rosa Tarrio, Patricia Blancoarias, Susana Teijeira, Francisco Rodrigueztrelles, Maria Garciamurias, Valerie Delague, Nicolas Levy
    Abstract:

    Abstract This study aimed to identify the Genetic defect in a multigenerational family presenting an autosomal dominant myopathy with histological features of congenital fiber type disproportion. Linkage analysis and Genetic Sequencing identified, in all affected members of the family, the c.5807A>G heterozygous mutation in MYH7 , which encodes the slow/β-cardiac myosin heavy chain. This mutation causes skeletal but not cardiac involvement. Myosin heavy chain expression pattern was also characterized by immunohistochemistry, western blot and q-PCR in muscle biopsies from two patients aged 25 and 62, respectively. While only congenital fiber type disproportion was observed in the younger patient, older patient's biopsy presented aggregates of slow myosin heavy chains, in fiber sub-sarcolemmal region. These clinico-pathologic findings suggest a novel phenotype within the emerging group of hereditary myosin myopathies, which in this family presents typical characteristics of congenital fiber type disproportion in early stages and later evolves to myosin storage myopathy.
