Abstract:
Inherited homocystinuria is a rare autosomal recessive aminoacidopathy which through early diagnosis can prevent its severe neurologic and vascular complications. Here we report a 9-year-old girl with homocystinuria, presenting with sequential symptoms of bilateral lens dislocation, skeletal complication, and eventually dystonia from the age of 4 years. Laboratory evaluation revealed severe high serum homocysteine level. Although pathophysiologically unexplained, evidence of deep white matter watershed infarct along with remarkable ipsilateral carotid stenosis was detected on the contralateral side of the dystonia in the neuroimaging. Treatment with high dose of pyridoxine relieved limb and gait dystonia significantly, while carotid stenosis remained unchanged. Therefore, homocysteine might have both structural and irreversible effect and functional and reversible impact that could be overcome even in late stages.
