Project description:Novel candidate genes, including MIS18BP1, for Autism Spectrum Disorders identified by whole-exome sequencing in the Lebanese population
Project description:Ultimately, autism is classified as an early neurodevelopmental disorder, highly heterogeneous and with a heritability of between 40% and 90%. Transcriptome studies have already been done in subjects with autism, but we decided to perform such a study on our own cohort of Sicilian subjects with autism. the results obtained show the involvement of differentially expressed genes involving inflammatory mechanisms and the mitochondrilae system.
Project description:Diversity clinical phenotypes of autism spectrum disorders (ASD), caused by heterogeneity of genetic and environmental factors, hampered the investigation in uncovering pathological mechanisms. Here we generated ASD patient-cerebral organoids from induced pluripotent stem cells (iPSCs) that reprogramed from the early-onset ASD individuals at around 2 years old with common clinical diagnosis in a prospective birth cohort, which was excluded typical autistic mutations and environmental exposures.
Project description:Individualized outcome prediction classifiers were successfully constructed through expression profiling of 91 up-regulated and 67 down-regulated miRNAs in 5 autism spectrum disorder (ASD) cases and 5 controls. In the study presented here, a well-defined cohort of 5 autism spectrum disorder cases and 5 controls was used to acquire expression profiles of 91 up-regulated and 67 down-regulated miRNAs, leading to the first global miRNA expression profile of ASD in China.
