Probing matters of the heart

t for cardiac development. Defects in many of these transcription factors have previously been linked to congenital heart defects.

Linking disease with DNA

Previous genome-wide sequencing studies have revealed genetic variations that are more common in people with congenital heart disease or cardiovascular disease. The data obtained in this study should help researchers figure out why those variations give rise to such diseases.

The researchers are now looking for other combinations of transcription factors that are involved in controlling cardiac differentiation. They are also studying variations in the regulatory sequences they identified to figure out how these sequences might give rise to congenital heart disease or susceptibility to cardiovascular disease later in life.
