AbstractThe 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. Two known mutations were described in two different cases. Heterozygous S14L was determined in one patient and heterozygous L748I was determined in another patient. The S14L and L748I mutations have been described in the patients with autism before. Both of these mutations were inherited from their father. In this study, two of 30 (6.7%) autism spectrum disorder (ASD) patients carrying NRXN1 gene mutations were detected. It indicates that variants in the NRXN1 gene might confer a risk of developing nonsyndromic ASD. However, due to the reduced penetrance in the gene, the causal role of the NRXN1 gene mutations must be evaluated carefully in all cases.

The review presents an analysis of the mechanisms of iron effect on the brain development. The importance of iron deficiency in the perinatal period is considered as a risk factor for the development of neuropsychiatric disorders in children with autism spectrum disorders (ASDs). Possible causes of sideropenia are discussed; data on haematological and biochemical parameters characterizing iron metabolism in children with ASDs are presented. The demand for studying the role of iron metabolism imbalance in the development of neuropsychiatric disorders in order to clarify pathogenetic mechanisms of ASDs and to determine methods for their correction is emphasized.
