Complex Glycerol Kinase Deficiency (Xp21 Deletion Syndrome): A Case Report of a Contiguous Gene Disorder Necessitating Creative Anesthetic Planning

Abstract

We report a case of Xp21 deletion syndrome, a contiguous gene syndrome associating glycerol kinase deficiency, Duchenne muscular dystrophy, and congenital adrenal hypoplasia. This results in a contraindication to the use of all halogenated agents and of propofol. We used regional anesthesia combined with dexmedetomidine and ketamine. Previously, the patient had received inadvertently a propofol-based total intravenous anesthesia (TIVA) with no clinical side effects. We were unfortunately unable to document the metabolic consequences of this glycerol load. We suggest that if propofol is deemed necessary in such cases, it should only be used as a bolus dose of a 2% solution.
