Diagnostic yield and treatment impact of whole-genome sequencing in paediatric neurological disorders.

WGS allows paediatric neurologists to integrate genomic data into their diagnosis and adjust management strategies for a range of clinical and genetically heterogeneous disease entities to improve the clinical outcomes of patients. In our cohort, the diagnosis of a significant proportion of patients was reached through WGS (43.9%). Clinicians could use these results to directly guide the management of their patients and improve their clinical outcomes (23.4%). What this paper adds For selected children in our cohort, the diagnostic yield of whole-genome sequencing (WGS) was 43.9%. WGS can be used to expand our knowledge of phenotype-genotype variations.
