ISL1 common variant rs1017 is not associated with susceptibility to congenital heart disease in a Chinese population.

ABSTRACT:

Background

ISL1, as a member of the LIM homeodomain transcription factor family, is expressed in a distinct population of undifferentiated cardiac progenitors and plays a pivotal role in cardiogenesis. Lacking ISL1 expression results in growth arrest or displays profound defects in heart development, including atria, ventricle, and the inflow and outflow tracts, which constitute a major form of congenital heart disease (CHD). Recently, an important study by Stevens et al. found that genetic variation in ISL1 is associated with risk of CHD in white and black/African American populations; this observation led us to hypothesize that ISL1 common variants might influence susceptibility to sporadic CHD in our Chinese population.

Methods

We conducted a case-control study of CHD in
