E74.820
SLC13A5 Citrate Transporter Disorder
Clinical Classification Guidelines
Medical Intelligence & Overview
SLC13A5 Citrate Transporter Disorder is a rare genetic condition that impacts the body's ability to manage citrate, a vital compound involved in energy production and other cellular processes. This disorder results from mutations in the SLC13A5 gene, which provides instructions for making a transporter protein responsible for moving citrate across cell membranes. The dysfunction of this transporter can lead to neurological symptoms, developmental delays, and metabolic disturbances.
Causes & Symptoms
Clinical Causes: Mutations in the SLC13A5 gene, inherited in an autosomal recessive pattern Rare genetic changes that affect the citrate transporter protein's function No known environmental or lifestyle factors directly cause this disorder
Key Symptoms: Early-onset seizures, often within the first months of life Developmental delays in motor skills and speech Intellectual disabilities Suppressed or abnormal muscle tone (hypotonia or hypertonia) Behavioral issues such as irritability or hyperactivity Possible microcephaly (smaller head size) Uncommon features may include growth delays and abnormal eye movements
Diagnostic & Treatment
Diagnosis Path: Detailed developmental and medical history review Neurological examination to assess motor skills and reflexes Brain imaging studies like MRI to look for abnormalities Genetic testing, including DNA analysis to identify mutations in the SLC13A5 gene Electroencephalogram (EEG) to evaluate seizure activity Metabolic tests to assess citrate levels and related metabolites
Treatment Protocols: Antiepileptic medications to control seizures Physical therapy to support motor development Speech and language therapy for communication skills Occupational therapy to enhance daily living skills Regular developmental assessments and support services Monitoring for potential metabolic or nutritional concerns
