Clinical Scorecard: Genomics Reveals Causes of Cerebral Palsy

At a Glance

Key Highlights

• WGS identified pathogenic or likely pathogenic variants in 11 of 86 children; eight additional children had potentially relevant variants that were insufficient to establish a diagnosis.
• All 11 confirmed genetic diagnoses influenced care or genetic counselling.
• Four children received tailored clinical management and seven required additional specialist care.
• Intellectual disability, dystonia, and abnormalities affecting multiple body systems were associated with greater diagnostic probability.
• The authors noted that larger prospective studies are needed to assess diagnostic effectiveness, cost-effectiveness, and appropriate patient selection.

Guideline-Based Recommendations

Diagnosis

• The study supports considering WGS in diagnostic pathways for children with cerebral palsy, particularly when additional clinical features suggest an underlying genetic condition.
• The study used WGS, usually alongside biological parents, with AI software to prioritize potentially disease-causing variants.
• The authors report that broad genome analysis combined with targeted gene lists and multidisciplinary variant interpretation can identify diagnoses that analysis restricted to established cerebral palsy genes might miss.
• The researchers developed a machine-learning model using standardized clinical descriptions to identify children more likely to receive a genetic diagnosis; it achieved an area under the curve of 0.88.

Patient & Prescribing Data

The UK pilot study recruited 86 children with cerebral palsy from five NHS specialist clinics in England.

Among 11 children with pathogenic or likely pathogenic variants, four received tailored clinical management and seven required additional specialist care. One example was a change in antiseizure medication following identification of an SCN1A variant.

Clinical Best Practices

• Consider the possibility of an underlying genetic condition in children with cerebral palsy, particularly when additional clinical features are present.
• Interpret genomic findings using broad genome analysis, targeted gene lists, and multidisciplinary variant review, as described in the study.
• Distinguish confirmed pathogenic or likely pathogenic findings from potentially relevant variants that are insufficient to establish a diagnosis.
