QA0.0142

DLG4-related synaptopathy

Clinical Classification Guidelines

Medical Intelligence & Overview

DLG4-related synaptopathy refers to a neurological condition involving abnormalities in synapses, the connections between nerve cells, caused by alterations in the DLG4 gene. This gene encodes for a protein called PSD-95, which plays a vital role in synaptic structure and function. Disruptions in this protein can impair the communication between neurons, potentially leading to neurological and developmental issues. Although this specific condition is relatively rare and less widely studied, understanding its underlying mechanisms can provide insight into certain neurodevelopmental and neuropsychiatric disorders where synaptic dysfunction is a key feature.

Causes & Symptoms

Clinical Causes: Genetic mutations or alterations in the DLG4 gene Inherited genetic predispositions De novo mutations occurring spontaneously Potential environmental factors influencing gene expression (though less well-established)

Key Symptoms: Developmental delays or intellectual disabilities Learning difficulties Speech and language impairments Behavioral challenges, including social interaction issues Seizures or abnormal neural activity Motor coordination problems Hypotonia (reduced muscle tone)

Diagnostic & Treatment

Diagnosis Path: Diagnosing DLG4-related synaptopathy involves a combination of clinical assessment and genetic testing. Healthcare providers typically evaluate developmental history and neurological function, followed by laboratory investigations such as:

Treatment Protocols: Currently, there is no specific cure for DLG4-related synaptopathy. Treatment approaches focus on managing symptoms and improving quality of life, including:

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
