  • Title: A dystrophin missense mutation showing persistence of dystrophin and dystrophin-associated proteins yet a severe phenotype.
    Author: Goldberg LR, Hausmanowa-Petrusewicz I, Fidzianska A, Duggan DJ, Steinberg LS, Hoffman EP.
    Journal: Ann Neurol; 1998 Dec; 44(6):971-6. PubMed ID: 9851445.
    Abstract:
    A muscle biopsy from an X-linked muscular dystrophy pedigree showed normal dystrophin and dystrophin-associated proteins. Linkage to multiple markers within the dystrophin gene (LOD=2.7, theta=0) indicated a primary dystrophinopathy. Sequencing of the entire dystrophin RNA revealed a single missense mutation (D3335H) in the unique carboxyl-terminal domain. This is the first report showing that a relatively severe dystrophinopathy can occur despite the correct localization of dystrophin and dystrophin-associated proteins.
