Principal component analysis of gene expression profiles of LCLs from individuals with DS and with CHD: red- AVSD (nâ=â7); green- ASD (nâ=â8); blue- VSD (nâ=â6).
<p>Red circle indicates AVSD, blue circle indicates ASD and VSD.</p
Transcriptome signature of heart defects.
<p>Comparison of ratios for DE genes up- or down-regulated in the AVSD or ASD+VSD group between (1) array ratio in the Ts21 CHD<sup>â</sup> vs 2N, (2) array ratio in CHD<sup>+</sup> vs CHD<sup>â</sup>, (3) q-PCR ratio from different experiments in CHD<sup>+</sup> vs CHD<sup>â</sup> using additional samples (total number in parentheses).

GO categories in the CDH<sup>+</sup> DE genes.
<p>Analysis of the enrichment of GO categories for the genes DE in the comparison between AVSD or ASD+VSD set of genes and CHD<sup>â</sup> set of genes compared to the genes expressed in LCLs. Analysis used GOrilla software with a p-value threshold at 10<sup>â3</sup>. N - is the total number of genes, B - is the total number of genes associated with a specific null, n - is the number of genes in the group with heart defect, b - is the number of genes in the intersection.</p
Classification of heart defects (CHD+) according to the distribution frequency of their p-values.
<p>Empirical cumulative distributions of p-values for the 2-by-2 Student tests A: AVSD/ASD; B: AVSD/VSD; C: ASD/VSD. Comparisons were obtained for 11 224 tests. The comparison to the uniform distribution shows that there is no overall differential expression between ASD and VSD (less small p-values than for an uniform distribution). Cdf: cumulative distribution function.</p
