This study emerged from an urgent clinical need. We evaluated 54 children with unexplained neurological and metabolic symptoms at our center. Many of these patients had a history of consanguinity and had previously undergone long diagnostic journeys without clear answers. By applying WES, we identified pathogenic or likely pathogenic variants in 52% of cases and clinically relevant findings in 83%, including 14 novel mutations not previously reported.
Beyond diagnosis, WES had a direct impact on patient care:
Diagnostic reclassification occurred in 83% of cases
Treatment plans were adjusted in 74% of cases
Prognostic clarity and preventive counseling became possible for the majority of families
Our work highlights the transformative role of WES in diagnosing rare pediatric conditions, particularly in populations with high consanguinity and limited access to traditional genetic services. We hope this study encourages the integration of genomic diagnostics into neurology and pediatrics in similar settings worldwide.
