title: Argininosuccinic aciduria: from a monogenic to a complex disorder.
abstract: In the early 1930s, phenylketonuria was among the first metabolic diseases to be defined. In the following years, multiple attempts to correlate genotype and phenotype in several inherited metabolic diseases, including phenylketonuria, were encountered with difficulties. It is becoming evident that the phenotype of metabolic disorders is often more multifaceted than expected from the disruption of a specific enzyme function caused by a single-gene disorder. Undoubtedly, revealing the factors contributing to the discrepancy between the loss of a single enzymatic function and the wide spectrum of clinical consequences would allow clinicians to optimize treatment for their patients. This article discusses several possible contributors to the unique, complex phenotypes observed in inherited metabolic disorders, using argininosuccinic aciduria as a disease model.Genet Med 2013:15(4):251-257.
