Isovaleric Acidemia (IVA) is an autosomal recessive Inborne Error of Metabolism (IEM), i.e., caused by the mutation of isovaleric-CoA dehydrogenase. Two phenotypes of IVA are reported; acute and chronic. The case was a 3-year-old boy with chronic intermittent presentation. Elevated 3-hydroxybutyric acid and isovaleric glycine in urinary acid profile was reported. We also performed a brief review about the presented case; IVA in international databases for English language articles on children. Several manners exist to screen IVA patients and the best one is GC-MS in urine analysis. The prognosis of the disease depends on the early interventions.
