E72.0
Disorders of amino-acid transport
Clinical Classification Guidelines
Excludes Type 1
- disorders of tryptophan metabolism (E70.5)
Medical Intelligence & Overview
Disorders of amino-acid transport are rare genetic conditions that affect how the body moves amino acids, the building blocks of proteins, into and out of cells. These transport issues can lead to imbalances in amino acids within the body, impacting growth, development, and overall health. The ICD-10 code E72.0 specifically designates this group of disorders, which are inherited and often require specialized management.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting amino acid transport proteins Inheritance patterns, typically autosomal recessive Disruption of normal amino acid movement across cell membranes
Key Symptoms: Poor feeding or loss of appetite in infants Failure to thrive or poor growth Developmental delays or intellectual disabilities Muscle weakness or hypotonia Seizures in some cases Unusual odor or skin changes from amino acid buildup
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical evaluation, biochemical tests, and genetic analysis. Blood and urine tests can detect abnormal amino acid levels, while molecular genetic testing confirms specific mutations affecting amino acid transporters. Functional assays in specialized labs may assess the transport activity directly.
Treatment Protocols: Management strategies focus on controlling amino acid levels and supporting overall health. Dietary modifications may include specialized low-protein diets tailored to reduce amino acid buildup. In some cases, supplementation of specific amino acids is necessary. Regular monitoring by healthcare professionals ensures that metabolic balance is maintained. Supportive therapies, including physical, occupational, and speech therapy, might be recommended to assist with developmental challenges. Pharmacological treatments are generally tailored to individual needs, depending on the specific disorder.
