For decades, families of children with cerebral palsy have sought refuge in genetic explanations, hoping that a named mutation might end their diagnostic wandering. A new study published in The American Journal of Human Genetics now reveals that of 515 genes previously identified as causes of the condition, only 89 carry convincing statistical evidence of a true link — a finding that asks medicine to reckon with the difference between correlation and causation in an era of abundant but imperfectly interpreted genomic data. The stakes are not merely academic: a false genetic answer can quietly
Study challenges cerebral palsy genetic links, finds only 89 of 515 proposed genes have real evidence
Misdiagnosis based on false genetic associations can delay discovery of treatable conditions in children with cerebral palsy, affecting their developmental outcomes and quality of life.
