基因组拷贝数变异 (CNV) 与染色体畸变或单基因突变一样导致先天性心脏病 (CHD) 病例 (10-15%),并影响临床结果。一些基因组热点(1q21.1、2q13、8p23.1、11q24、15q11.2、16p11.2 和 22q11.2)中的 CNV 在 CHD 人群中反复富集,并影响心脏发育所需的剂量敏感转录调节因子。外显率降低以及对大脑和心脏发育的多效性影响是这些 CNV 的共同特征。因此,在大多数情况下,可能需要额外的基因“打击”,例如第二次 CNV 或基因突变,才能引起冠心病。需要对 CNV、基因组序列、表观遗传改变和基因功能进行综合分析,以描绘 CHD 的完整遗传图谱。
Genomic copy-number variants (CNVs) contribute to as many congenital heart disease (CHD) cases (10-15%) as chromosomal aberrations or single-gene mutations and influence clinical outcomes. CNVs in a few genomic hotspots (1q21.1, 2q13, 8p23.1, 11q24, 15q11.2, 16p11.2, and 22q11.2) are recurrently enriched in CHD cohorts and affect dosage-sensitive transcriptional regulators that are required for cardiac development. Reduced penetrance and pleiotropic effects on brain and heart development are common features of these CNVs. Therefore, additional genetic 'hits,' such as a second CNV or gene mutation, are probably required to cause CHD in most cases. Integrative analysis of CNVs, genome sequence, epigenetic alterations, and gene function will be required to delineate the complete genetic landscape of CHD.
