Brief Summary

The role of gut microbiome was recently raised in the pathogenesis of neurodevelopmental disorders including autism spectrum disorder (ASD). In view of these evidences, together with poor conductance of researches on gut microbiota in ASD patients in Egypt, in addition to the absence of definite medical test or biological marker for diagnosis of ASD, the present study is designed to study clinical risk factor of autism and the predominant gut microbiome in autistic children in an attempt to identify gut bacteria which are likely related to ASD and to correlate these bacteria and clinical variables with the severity of autism. Interestingly, the totality of the studies focusing on the fecal metabolome features in ASD has investigated the differences between subjects with and without this disorder, while ignoring potential correlations between microbiome, metabolome and ASD severity
