- Abstract
Background Congenital heart disease ( CHD) is one of the most common birth defects in newborns. The etiology of CHD has remained largely unknown, but it is assumed to result from the combined effects of genetic and environmental factors. Recent investigations have detected potentially pathogenic copy number variations ( CNV) in a proportion of patients with CHD. The present case-control study evaluated whether CNV in the GATA4 and NKX2-5 genes contribute to the pathogenesis of CHD in Chinese fetuses ( n = 117), by comparing them with non- CHD control subjects ( n = 100). Methods Multiplex ligation-dependent probe amplification with the P311A probe mixture was used to detect CNV. Results The normalized signals were within the normal range for all exons in all CHD patients and non- CHD control subjects. Of the 117 CHD patients, three had a deletion of 22q11, and two had a duplication of 22q11. Conclusions There was no evidence of a role for NKX2-5 and GATA4 CNV in fetal CHD; therefore, these CNV may not be common in fetal CHD in China.
