Genes affected

HAND2 (HGNC:4808): (heart and neural crest derivatives expressed 2) The protein encoded by this gene belongs to the basic helix-loop-helix family of transcription factors. This gene product is one of two closely related family members, the HAND proteins, which are asymmetrically expressed in the developing ventricular chambers and play an essential role in cardiac morphogenesis. Working in a complementary fashion, they function in the formation of the right ventricle and aortic arch arteries, implicating them as mediators of congenital heart disease. In addition, this transcription factor plays an important role in limb and branchial arch development. [provided by RefSeq, Jul 2008]

HAND2 links:

HAND2-AS1 (HGNC:48872): (HAND2 antisense RNA 1) Predicted to be involved in positive regulation of gene expression. Predicted to act upstream of or within with a positive effect on cardiac right ventricle morphogenesis. Predicted to act upstream of or within transcription elongation from RNA polymerase II promoter. Predicted to be located in chromatin; cytoplasm; and nucleoplasm.
