NIH Rare Diseases : ⁵⁴ Glutathione synthetase deficiency is a genetic metabolic disorder that affects the body�??s ability to produce an important substance called glutathione. People with glutathione synthetase deficiency do not have enough of the molecule called glutathione synthetase, which helps the body produce glutathione. People with glutathione synthetase deficiency can have mild, moderate, or severe disease. The signs and symptoms of the deficiency may include anemia, the buildup of too much acid in the body (metabolic acidosis), frequent infections, and symptoms caused by problems in the brain including seizures, intellectual disability, and loss of coordination (ataxia).   Glutathione synthetase deficiency is caused by genetic changes (pathogenic variants or mutations) in the GSS gene. The deficiency is inherited in an autosomal recessive manner. Diagnosis of a metabolic disorder such as glutathione synthetase deficiency may be suspected when a doctor observes signs of the deficiency including metabolic acidosis. A doctor may order tests to confirm the diagnosis including enzyme assays, urine analysis, and genetic testing. Treatment for glutathione synthetase deficiency may include sodium bicarbonate to treat metabolic acidosis and taking vitamin supplements.

MalaCards based summary : Glutathione Synthetase Deficiency, also known as pyroglutamic aciduria, is related to hemolytic anemia and glutathione synthetase deficiency of erythrocytes, hemolytic anemia due to, and has symptoms including vomiting, abdominal pain and diarrhea. An important gene associated with Glutathione Synthetase Deficiency is GSS (Glutathione Synthetase), and among its related pathways/superpathways are Metabolism and Arachidonic acid metabolism. Affiliated tissues include brain, testes and neutrophil, and related phenotypes are hemolytic anemia and abnormality of immune system physiology

Genetics Home Reference : ²⁶ Glutathione synthetase deficiency is a disorder that prevents the production of an important molecule called glutathione. Glutathione helps prevent damage to cells by neutralizing harmful molecules generated during energy production. Glutathione also plays a role in processing medications and cancer-causing compounds (carcinogens), and building DNA, proteins, and other important cellular components.

OMIM : ⁵⁸ Glutathione synthetase deficiency, or 5-oxoprolinuria, is an autosomal recessive disorder characterized, in its severe form, by massive urinary excretion of 5-oxoproline, metabolic acidosis, hemolytic anemia, and central nervous system damage. The metabolic defect results in decreased levels of cellular glutathione, which overstimulates the synthesis of gamma-glutamylcysteine and its subsequent conversion to 5-oxoproline (Larsson and Anderson, 2001).
