Congenital Type II fibre deficient myopathy


A case of non-progressive congenital myopathy in a 14-month old male infant is described. The disorder is characterised histologically by a complete absence of Type II muscle fibres, hypoplastic Type I fibres of variable size and enlarged sarcolemmal nuclei. A neurogenic basis is proposed for this new myopathy.
