Congenital systemic glutamine deficiency (CSGD) is a rare developmental disorder with severe brain malformation resulting in multi-organ failure and neonatal death. Glutamine synthetase plays a major role in ammonia detoxification, interorgan nitrogen flux, acid-base homeostasis, and cell signaling. It has been reported that glutamine was largely absent from affected patients serum, urine, and cerebrospinal fluid.
