Figure Lengend Snippet: a , Schematic workflow going from hiPS cells to cortical organoids to sequencing data. The number of hiPS cell lines and individuals (in parentheses) for each form of ASD and controls is indicated. b , Schematic representation of hCO differentiations derived from each hiPS cell line for two forms of ASD (16p11.2 deletion and 22q13.3 deletion). The other forms of ASD can be found in Extended Data Fig. . c , Spearman’s correlation of gene expression between samples from the same time point and form of ASD that were derived either from different lines (red) or from the same line (blue). The sample sizes for each group (number of differentiations) are as follows: day 25: control lines, n = 46; 15q13.3del, n = 7; 16p11.2del, n = 5; 16p11.2dup, n = 4; 22q11.2del, n = 13; 22q13.3del, n = 11; idiopathic, n = 12; PCDH19, n = 2; SHANK3, n = 2; and Timothy syndrome, n = 3. Day 50: control lines, n = 53; 15q13.3del, n = 7; 16p11.2del, n = 6; 16p11.2dup, n = 4; 22q11.2del, n = 15; 22q13.3del, n = 12; idiopathic, n = 15; PCDH19 , n = 2; SHANK3, n = 2; and Timothy syndrome, n = 3. Day 75: control lines, n = 54; 15q13.3del, n = 7; 16p11.2del, n = 6; 16p11.2dup, n = 4; 22q11.2del, n = 23; 22q13.3del, n = 12; idiopathic, n = 15; PCDH19, n = 2; SHANK3, n = 2; and Timothy syndrome, n = 2. Day 100: control lines, n = 50; 15q13.3del, n = 6; 16p11.2del, n = 6; 16p11.2dup, n = 4; 22q11.2del, n = 15; 22q13.3del, n = 12; idiopathic, n = 15; PCDH19, n = 2; SHANK3, n = 2; and Timothy syndrome, n = 2. Boxplots show: centre, median; lower hinge, 25% quantile; upper hinge, 75% quantile; lower whisker, smallest observation greater than or equal to lower hinge −1.5× interquartile range; upper whisker, largest observation less than or equal to upper hinge +1.5× interquartile range. d , Genes within the CNVs are downregulated in deletions and upregulated in duplications, as exemplified by 16p11.2 deletion (del) and duplication (dup) and 15q13.3 deletion. 16p11.2del, 61.5% of genes; 16p11.2dup, 50% of genes and 15q13.3del, 52.9% of genes. *dreamlet P values of less than 0.005.

Article Snippet: To control for technical variation due to the sequencing and library prep we calculated the principal components of the Picard sequencing metrics ( http://broadinstitute.github.io/picard/ ) using the CollectAlignmentSummaryMetrics, CollectRnaSeqMetrics and MarkDuplicates modules, and included them in our model. To infer genetic ancestry, we called single-nucleotide polymorphisms (SNPs) from the aligned reads using the GATK (v.3.3) Haplotype caller .
