The clinical and neuropathological findings are described in two children with propionic acidaemia presenting in infancy; they survived for 4 and 16 years respectively. Abnormalities were noted in the basal ganglia of both patients. In one child who clinically had severe athetosis, there was marbling of the corpus striatum. Clinical and morphological evidence suggests that the basal ganglia are especially vulnerable in propionic acidaemia.

Objectives: Acrodermatitis dysmetabolica (AD) is a dermatologic manifestation associated with inherited metabolic disorders (IMDs), distinct from acrodermatitis enteropathica, which occurs solely due to zinc deficiency.
Case Presentation: This report presents two pediatric cases: a 30-month-old girl with maple syrup urine disease (MSUD) experiencing AD secondary to severe isoleucine deficiency due to a protein-restricted diet, showing improvement with dietary adjustments, and a 2.5-month-old boy infant with propionic acidemia (PA) who developed AD alongside septic shock, which progressed despite intervention.

Propionic aciduria (PA) and methylmalonic aciduria (MMA) are rare inherited disorders caused by defects in the propionate metabolic pathway. PA due to propionyl coenzyme A carboxylase deficiency results in accumulation of propionic acid, while in MMA, deficiency in methylmalonyl coenzyme A mutase leads to accumulation of methylmalonic acid. Hyperammonemia is related to a secondary deficiency of N-acetylglutamate (NAG), the activator of carbamoyl phosphate synthetase 1, which is an irreversible rate-limiting enzyme in the urea cycle.

Mutations in the mitochondrial enzyme propionyl-CoA carboxylase (PCC) cause propionic aciduria (PA). Chronic kidney disease (CKD) is a known long-term complication. However, good metabolic control and standard therapy fail to prevent CKD.

Background: Propionic acidemia (PA) is an inborn error of metabolism (IEM) that typically presents in the newborn. The Amish of North America have an increased prevalence of PA due to a founder variant in the gene. The Amish PA phenotype is variable, and some individuals remain asymptomatic and undiagnosed until adulthood.
