muscular dystrophy

muscular dystrophy
A group of diseases characterized by progressive degeneration and/or loss of muscle fibres without nervous system involvement. All or nearly all of them have a hereditary origin but details of the type of genetic defect and of the prognosis for the disease vary from type to type. Duchenne MD (pseudohypertrophic MD) is the most common form. It is due to a sex-linked recessive allele and this is expressed as an absence of the protein dystrophin; the disease in boys shows extensive but insufficient muscle fibre reformation from satellite cells.
