Hemolytic Anemia Due to Gamma-Glutamylcysteine Synthetase Deficiency: A Rare Novel Case in an Arab-Muslim Israeli Child

This study reports a rare case of gamma-glutamylcysteine synthetase deficiency in a 4.11-year-old Arab-Muslim boy from Israel who presented with severe anemia at 2 days old, aiming to document the first such case in the Middle East and contribute to the medical literature on this extremely rare condition that has only been detected in nine patients worldwide. Genetic analysis revealed a homozygotic change in the GCLC gene, confirming the diagnosis, and while the patient experiences chronic anemia, he maintains normal physical and neurological development, adding valuable insights to the understanding of this rare genetic disorder. An additional rare change was found in this case in the GCLC gene, with unknown clinical significance: g.53373917, c 828 + 3A > G.
