Clinical Scorecard: Diverse Clinical Presentations and Diagnostic Difficulties in Neurodevelopmental Disorders Associated with CASK: A Longitudinal Observational Analysis

At a Glance

Key Highlights

• CASK variants lead to a spectrum of X-linked phenotypes from severe neurodevelopmental impairment to mild intellectual disability.
• Clinical presentations include MICPCH, developmental impairment, abnormal muscle tone, and epilepsy.
• Marked intrafamilial phenotypic variability complicates diagnosis.
• Comprehensive genetic testing is essential for accurate diagnosis of CASK-related disorders.
• Epilepsy is a common feature, with variable onset and types.

Guideline-Based Recommendations

Diagnosis

• Utilize next-generation sequencing for patients with clinical features suggestive of CASK-related disorders.

Management

• Monitor developmental progress and manage associated symptoms such as epilepsy.

Monitoring & Follow-up

• Regular follow-up assessments of neurodevelopmental status and seizure activity.

Risks

• Delayed diagnosis due to absence of characteristic neuroimaging findings.

Patient & Prescribing Data

Pediatric patients diagnosed with CASK-related disorders

Management strategies should be individualized based on the specific clinical presentation.

Clinical Best Practices

• Conduct thorough clinical evaluations including neurological assessments.
• Implement genetic testing when CASK-related disorders are suspected.
• Consider multidisciplinary approaches for managing complex presentations.
