  • Title: Limb girdle muscular dystrophy: description of a phenotype.
    Author: Stübgen JP.
    Journal: Muscle Nerve; 1994 Dec; 17(12):1449-55. PubMed ID: 7969245.
    Abstract:
    The phenotype is reported of 20 patients with autosomal recessive or sporadic, pelvifemoral limb girdle muscular dystrophy (LGMD). Selective wasting of muscles was observed at the moderately advanced stage of illness. The pattern of weakness was uniform. Attention to clinical detail allowed the identification of a phenotype different from a hypothetical scheme of LGMD based on previous literature, and other causes of limb girdle weakness. These patients may represent yet another nosologic entity within the autosomal recessive dystrophies; molecular genetic studies are awaited. A limited magnetic resonance imaging (MRI) study of muscle was of little consequence. Although additional detail was obtained, no pathognomonic distribution of the dystrophic process was observed; interindividual variation existed even among closely matched siblings. The severity of MRI signal change did not consistently correlate with the degree of weakness in an individual. When a diagnosis is uncertain, however, the added detail may be useful.
