title: Chromosome deletion and multiple cartilaginous exostoses.
abstract: We report a 13 year-old girl with manifestations strikingly reminiscent of the tricho-rhino-phalangeal (TRP) II or Langer-Giedion syndrome. A terminal deletion of 8q must be assumed to be the cause of her condition till proven otherwise. A similar chromosome abnormality should be searched for (blindly) in other cases of the TRP II previously thought to have had normal chromosomes.
