6q25.1 microdeletion, the TAB2 gene plays a key role in congenital heart defects
American Journal of Medical Genetics March 2017 Congenital heart defects (CHD) affect approximately 1.35 million infants each year. New technologies have revealed more genetic causes for CHD; one gene of interest is TAB2 (Full name: TGF-beta activated kinase 1/MAP3K7 binding protein 2) which, as the study finds, causes structural valve...
