The aim of this study was to identify the sequence mutations in the Neurexin 1 (NRXN1) gene that has been considered as one of the strong candidate genes. A total of 30 children and adolescents (aged 3-18) with non syndromic autism were enrolled this study. Sequencing of the coding exons and the exon-intron boundaries of the NRXN1 gene was performed. https://www.halohealthcarers.shop/product-category/30-40mmhg/
