Schinzel-Giedion syndrome: evidence for a neurodegenerative process

We report on a case of Schinzel-Giedion syndrome in which serial magnetic resonance (MR) brain-imaging studies demonstrated a progressive neurodegenerative process. These findings in addition to "coarse" facial appearance and skeletal abnormality suggest that a progressive metabolic defect underlies this syndrome. However, results of detailed investigations for metabolic disorder were all normal.
