[Smith-McCort syndrome (author's transl)].

An 13-year-old mentally normal boy with short-trunked dwarfism is discribed as a case of the Smith-McCort syndrome (SMC-syndrome). His disease has been observed radiologically, clinically an histologically for many years. According to Spranger (23) this disorder differs from the Dyggve-Melchior-Clausen disease (DMC-syndrome) by lacking oligophrenia. Beside a characteristic flattening of the vertebral bodies both syndromes show a lacelike appearance of the iliac crest (crest sign) as a significant radiological sign. Both syndromes appear to be inherited as an autosomal recessive trait.
