Abstract:
Objective To explore the genetic etiology of a girl featuring epilepsy,speech delay and mild mental retardation.Methods Peripheral blood samples of the child and her parents were collected.Genomic DNA was extracted and subjected to next generation sequencing.Suspected variant was confirmed by Sanger sequencing.Results The child was found to carry a de novo heterozygous c.3592G> A (p.V1198M) variant of the SMARCA2 gene,which was predicted to be pathogenic by bioinformatic analysis.Conclusion The child was diagnosed with Nicolaides-Baraitser syndrome due to heterozygous variant of the SMARCA2 gene.
