Research Abstract

Among the 203 trio autism families, 191 were simplex, while the remaining 12 were multiplex. The samplese were analyzed using Affymetrix Genome-Wide Human SNP Nsp/Sty 6.0 microarray. Among a total of 7305 CNVs detected in affected children after all QC corrections, 3728 were found to be affecting genes. 89.6% of these were confirmed to be inheited from parents. Among the remaining 378 CNVs, 17 novel/ultra-rare de novo events were identified.Novel deletions were observed in genes involved in neurodevelopmental pathways such as SHANK3 et al..
