Figure 2.
Diagram of KCNQ1, KCNQ1OT1, and CDKN1C within the IC2 domain. (A) UCSC genome browser view of hg19 chr11:2 443 460–2 921 770 including ENCODE tracks of histone modifications and DNase hypersensitivity (HS) sites observed in H1-hESC samples. (B) A stylized diagram of the IC2 domain demonstrating the parent-of-origin gene expression in scale with the UCSC view. In both panels. The documented BWS-causing KCNQ1 5′ deletion is indicated by the gold box. Protein-coding genes (KCNQ1 and CDKN1C) antisense transcript (KCNQ1OT1) are indicated in purple. CpG islands within the region are displayed in green, while CTCF binding sites are highlighted in aqua. Capture C anchors and ChIP-qPCR primer sites are indicated by Region1-5 labels. Scale bar indicates 100 kb.
