Utility of exome sequencing for the diagnosis of pediatric-onset neuromuscular diseases beyond diagnostic yield: a narrative review.

Diagnosis of neuromuscular diseases (NMD) can be challenging because of the heterogeneity of this group of diseases. This review aimed to describe the diagnostic yield of whole exome sequencing (WES) for pediatric-onset neuromuscular disease diagnosis, as well as other benefits of this approach in patient management since WES can contribute to appropriate treatment selection in NMD patients. WES increases the possibility of reaching a conclusive genetic diagnosis when other technologies have failed and even exploring new genes not previously associated with a specific NMD. Moreover, this strategy can be useful when a dual diagnosis is suspected in complex congenital anomalies and undiagnosed cases.

Sobreposición del síndrome de Miller Fisher y encefalitis de Bickerstaff en pediatría: reporte de caso / Overlap of Miller Fisher syndrome and Bickerstaff encephalitis in pediatrics: Case report

RESUMEN Se describe el caso en pediatría de la sobreposición del síndrome de Miller Fisher y la encefalitis de Bickerstaff en presencia de perfil de anticuerpos positivos para anti-GQ1b en un niño de 6 años, quien presenta un compromiso tronco-encefálico y luego entra en una encefalopatía con compromiso de nervio periférico. El presente caso es relevante en relación con los escases de artículos semejantes en la literatura pediátrica, con pocos precedentes en la literatura publicada hasta la fecha.

SUMMARY To describe the pediatric case of the overlap of Miller Fisher syndrome and Bickerstaff encephalitis in the presence of an anti-GQ1b positive antibody profile in a 6-year-old boy who presents with a brainstem compromise and progress to encephalopathy with peripheral nerve compromise, the present case is relevant in relation to the scarcity of similar articles in pediatric literature with few precedents in the literature published to date.
