Summary

Sulfide:quinone oxidoreductase-deficiency (SQORD) is characterized by a variable phenotype ranging from no clinical symptoms to episodes of encephalopathy and Leigh syndrome-like (see 256000) brain lesions, with acute symptoms triggered by infections and fasting. Other features may include lactic acidosis and decreased mitochondrial respiratory chain complex IV activity in tissues. Most affected individuals are asymptomatic. Patients with encephalopathy may recover or die in childhood (Friederich et al., 2020). [from OMIM]
