Scientists implicate non-cardiac genes in congenital heart disease

Inside embryonic cells, specific proteins control the rate at which genetic information is transcribed from DNA to messenger RNA—a crucial regulatory step before proteins are created. Then, organs develop and hopefully function properly. Those specific "regulatory" proteins are called transcription factors, and they do their thing by binding to specific DNA sequences at just the right time.
