3-methylglutaconic aciduria

Mutations in AUH are associated with 3-methylglutaconic aciduria, a rare autosomal recessive disorder. AUH catalyzes the fifth step in the catabolism of leucine, the conversion of 3-methylglutaconyl-CoA to 3-hydroxy-methylglutaryl-CoA (Iljst et al, 2002; Ly et al, 2003; Mack et al, 2006). Mutations that affect AUH stability or function result in accumulation of metabolic intermediates such as 3-methylglutaconic acid, 3-methylglutaric acid and 3-hydroxyisovaleric acid that are excreted in urine (Duran et al, 1982; Ly et al, 2002; Mack et al, 2006; Nardecchia et al, 2022). The clinical presentation of 3-methylglutaconic aciduria is variable ranging from no-to-mild symptoms to severe encephalopathy, metabolic acidosis and coma (Nardecchia et al, 2022).
