Pediatric Cohort of Charcot-Marie-Tooth Disease

This study provides a description of pediatric CMT disease in a Canadian cohort. We show that while genetic distributions mirror international data, family-based genetic screening can identify children even before clinical onset, and that orthopaedic complications are already common in early childhood. These findings reinforce the importance of early genetic confirmation, orthopaedic surveillance, and expanded sequencing strategies to improve care and refine genotype-phenotype correlations in pediatric CMT disease.
