Genetic counseling considerations in cerebral palsy

Area of Science:

• Genetics
• Neurology
• Medical Diagnostics

Background:

• Cerebral palsy (CP) was historically attributed to birth injury but is increasingly recognized as having a significant genetic component.
• Genome-wide sequencing (GWS) has emerged as a powerful tool for diagnosing rare genetic disorders.
• Understanding the genetic basis of CP is crucial for tailored management and genetic counseling.

Purpose of the Study:

• To review advances in GWS for diagnosing cerebral palsy.
• To outline clinical features suggestive of a genetic etiology in CP.
• To provide guidance on genetic counseling for families undergoing GWS for CP.

Main Methods:

• Review of current literature on GWS in CP diagnosis.
• Analysis of clinical presentations indicative of genetic CP.
• Synthesis of international guidelines for GWS and genetic counseling.

Main Results:

• GWS has identified single-gene causes for a substantial number of CP cases.
• Genetic diagnoses inform customized treatment plans and management strategies.
• Genetic counseling is vital for pre- and post-test support, decision-making, and adaptation to genomic results.

Conclusions:

• GWS is transforming the diagnostic landscape for cerebral palsy, revealing numerous genetic etiologies.
• Genetic counseling is an essential component of GWS for CP, providing support and facilitating understanding.
• Establishing a genetic cause for CP has significant implications for patient care and family well-being.
