Diagnostic impact of whole exome sequencing in neurometabolic disorders in Syrian children: a single center experience
Published in Genetics & Genomics, General & Internal Medicine, and Paediatrics, Reproductive Medicine & Geriatrics
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.

The Emerging Frontiers of Genetic Screening in Inherited Disorders
The core challenge of modern preventive medicine is the accurate and timely identification of individuals at risk for genetic disorders. For decades, genetic testing has been gated by restrictive clinical criteria and "phenotype-first" models, which often rely on family history or specific symptoms to trigger a diagnostic workup. However, emerging evidence highlights a significant diagnostic gap: a substantial proportion of individuals carrying clinically actionable pathogenic variants are currently missed because they do not meet traditional testing guidelines or lack a documented family history of disease.
This Collection focuses on how the next generation of screening technologies can expand diagnostic capacity and maximize diagnostic yield. We are moving toward a "genome-first" era, in which criteria-independent testing and the integration of multimodal data enable the identification of individuals at risk who were previously undetected within the healthcare system. By leveraging advanced sequencing technologies and computational infrastructures, we can shift from reactive diagnostics to proactive, large-scale screening strategies that improve clinical outcomes across multiple medical disciplines.
Key Areas of Interest
We invite original research, reviews, and clinical perspectives that explore the technological and clinical pathways to increasing diagnostic sensitivity and specificity:
- Expanding the Diagnostic Net: Evaluating the clinical utility of criteria-independent or universal screening to identify high-risk individuals who would otherwise remain undetected under standard guidelines.
- Genome-First Implementation: Analysing the impact of population-based genomic screening in uncovering hereditary diseases or pathogenic variants associated with inherited diseases before the onset of clinical symptoms.
- Synergistic Diagnostic Modalities: The integration of DNA sequencing with other high-resolution markers, such as biochemical profiling or functional assays, to refine risk assessment and increase diagnostic precision.
- Opportunistic Screening and Secondary Findings: Best practices for managing and reporting actionable genetic findings discovered during routine clinical sequencing.
- Scalable Screening Architectures: Innovative approaches to integrating large-scale genetic data into healthcare systems, including the use of electronic health records to support automated risk identification.
- Overcoming Implementation Barriers: Strategies to mitigate disparities in access to screening, focusing on populations in which reliable family history information is limited.
