Congenital brain dysgenesis due to glutamine synthetase deficiency

Congenital brain dysgenesis due to glutamine synthetase deficiency is an extremely rare inherited metabolic disorder. It is also sometimes called glutamine synthetase deficiency or GS deficiency. The disease is caused by the body not making enough of an enzyme called glutamine synthetase. This enzyme is responsible for producing glutamine, one of the most important amino acids in the body. Without enough glutamine, the brain cannot develop properly before birth, and the nervous system is severely affected. Babies born with this condition typically have serious brain malformations that are present from birth. These include abnormal brain structure, very small brain size (microcephaly), and problems with the folds and layers of the brain. Because glutamine is critical for brain development and for controlling nerve signals, affected infants usually experience severe seizures that begin in the first days or weeks of life and are very difficult to control. Muscle tone is often very low, and babies may have trouble feeding and breathing. There is currently no cure for this condition. Treatment focuses on managing symptoms, especially seizures, and providing supportive care. Some research has explored whether giving glutamine supplements could help, but results have been limited. The overall outlook is very serious, and most affected children have profound developmental challenges. Early diagnosis through genetic testing is important for families to understand the condition and plan care.
