The 3D Interaction Viewer (3DIV) with the hg38 genome assembly showing the genomic context of chromosome 22q11.21 (top). The rs41298798-G/G MG63 cells show reduced expression of TBX1 compared to the C/C isogenic control (bottom). The results for each sample were normalized to its GAPDH content (n= 3 per genotype; the results are presented as mean ± SEM;*p≤ 0.05;**p≤ 0.01;****p≤ 0.0001; NS, not significant; Student’s t test).
