We report on 2 brothers with a distinctive facial appearance, severe mental retardation, short stature, cryptorchidism, asplenia in one, dramatic failure to thrive, early hypotonia, and later hypertonia all suggestive of the Smith-Fineman-Myers syndrome. All 5 of the reported cases have been males, suggesting X-linked inheritance.
