E72.5
Disorders of glycine metabolism
Clinical Classification Guidelines
Medical Intelligence & Overview
Disorders of glycine metabolism, classified under ICD-10 code E72.5, are rare inherited conditions that affect how the body processes glycine, an amino acid important for various biological functions. These conditions can lead to a buildup or deficiency of glycine in the body, resulting in a range of health issues. Understanding these disorders can help in early recognition and management, although they typically require specialized medical care.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting enzymes responsible for glycine breakdown or synthesis Inherited metabolic disorders passed from parents to offspring Autosomal recessive inheritance pattern in most cases Potential environmental factors that may influence symptom severity, although primary causes are genetic
Key Symptoms: Neurological issues such as seizures or developmental delays Hypotonia, or decreased muscle tone Irritability or abnormal movements in infants Poor feeding and difficulties gaining weight Possible behavioral problems or cognitive impairments Signs of glycine deficiency or excess depending on specific disorder type
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation, biochemical tests, and genetic analysis. Blood and cerebrospinal fluid (CSF) analyses can reveal abnormal glycine levels. Enzyme activity assays help determine specific metabolic defects. Genetic testing identifies mutations in genes responsible for glycine metabolism, confirming the diagnosis. Early diagnosis is critical for managing symptoms and preventing complications.
Treatment Protocols: Dietary modifications to control glycine intake Supplementation with cofactors or amino acids to support metabolic pathways Medications to manage seizures or neurological symptoms Regular monitoring of biochemical markers and neurological function Supportive therapies such as physical, occupational, or speech therapy to assist developmental progress
