Muscular biopsy shows aspecific myopathy. Intellectual development is normal. The syndrome is most likely inherited in an autosomal recessive manner. It differs from the Crisfield-Dretakis-Sharpe syndrome, in which short stature and muscular features are absent. Surgery of the scoliosis is necessary. Functional prognosis depends on the severity of the visual handicap."
