Summaries for Congenital Heart Defects, Multiple Types, 2

OMIM®: 57 Multiple types of congenital heart defects-2 (CHTD2) is characterized by variable congenital heart defects, primarily involving the valves, but also including septal defects or aneurysms, and complex defects such as tetralogy of Fallot. Dilated cardiomyopathy and myocardial noncompaction have been reported in some patients. In addition, some affected individuals exhibit facial dysmorphism and features of connective tissue disease (Thienpont et al., 2010; Ackerman et al., 2016; Ritelli et al., 2018). For a discussion of genetic heterogeneity of CHTD, see 306955. (614980) (Updated 08-Dec-2022)

MalaCards based summary: Congenital Heart Defects, Multiple Types, 2, is also known as chtd2. An important gene associated with Congenital Heart Defects, Multiple Types, 2 is TAB2 (TGF-Beta Activated Kinase 1 (MAP3K7) Binding Protein 2). Affiliated tissues include heart and skin, and related phenotypes are bicuspid aortic valve and tetralogy of fallot

UniProtKB/Swiss-Prot: 73 A disease characterized by congenital developmental abnormalities involving structures of the heart. CHTD2 patients have left ventricular outflow tract obstruction, subaortic stenosis, residual aortic regurgitation, atrial fibrillation, bicuspid aortic valve and aortic dilation.
