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]

The c.277G>C (p.G93R) alteration is located in exon 1 (coding exon 1) of the HAND2 gene. This alteration results from a G to C substitution at nucleotide position 277, causing the glycine (G) at amino acid position 93 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
