amino acid disorders
A group of inherited metabolic conditions affecting amino acid processing, detectable through newborn screening.
Full Definition
Amino acid disorders encompass a diverse group of autosomal recessive conditions caused by enzyme deficiencies in amino acid metabolic pathways. These disorders can lead to toxic accumulation of amino acids or their metabolites, resulting in intellectual disability, seizures, and other serious complications if untreated. Newborn screening typically identifies these conditions through amino acid analysis or specific enzyme assays, enabling early dietary interventions, enzyme replacement, or other treatments that can prevent or minimize clinical manifestations.
Usage
Usage note: Use 'amino acid disorders' as the preferred term rather than 'aminoacidopathies' in patient-facing materials.
