Copy number variations in the <i>GATA4</i>,<i> NKX2‐5</i>,<i> TBX5</i>,<i> BMP4 CRELD1</i>, and 22q11.2 gene regions in Chinese children with sporadic congenital heart disease

Abstract

These data suggest that copy number variation in the 22q11.2 region is common in CHD patients in southwest China. Regardless of the presence or absence of extracardiac symptoms, results also indicate that it is necessary to perform prenatal screening for CHD.
