CUX1 and Tetralogy of Fallot: Some new genes identified for RF-based CHD subtyping in cardiac fibroblasts have also been supported by recent publications like USP53 (Ubiquitin Specific Peptidase 53, 617431) in hypertrophic cardiomyopathy [94], CUX1 (cut like homeobox 1, 116896) for neo-hypoplastic left heart syndrome [95], and BAI3 (Brain-Specific Angiogenesis Inhibitor 3, 602684) for Tetralogy of Fallot [96].
