Abstract/OtherAbstract:
Late-onset glutaric aciduria type II has been described recently as a rare but treatable cause of proximal myopathy in teenagers and adults. It is an autosomal recessive disease affecting fatty acid, amino acid, and choline metabolism. This is usually a result of 2 defective flavoproteins: either electron transfer flavoprotein (ETF) or electron transfer flavoprotein-ubiquinone oxidoreductase (ETF:QO). We present a 14-year-old boy with a background of autistic spectrum disorder who presented with severe muscle weakness and significant rhabdomyolysis. Before the onset of muscle weakness, he was very active but was completely bedridden at presentation. Diagnosis was established quickly by urine organic acid and plasma acylcarnitine analysis. He has shown significant improvement after starting oral riboflavin supplementation and is now fully mobile. This case highlights that late-onset glutaric aciduria type II is an important differential diagnosis to consider in teenagers presenting with proximal myopathy and rhabdomyolysis and it may not be associated with hypoglycemia.
