Copy number variations (CNVs) comprise about 10% of reported disease-causing mutations in Mendelian disorders. Nevertheless, pathogenic CNVs may have been under-detected due to the lack or insufficient use of appropriate detection methods. In this report, on the example of the diagnostic odyssey of a patient with Marfan syndrome (MFS) harboring a hitherto unreported 32-kb deletion, we highlight the need for and the feasibility of testing for CNVs (>1 kb) in Mendelian disorders in the current next-generation sequencing (NGS) era.
拷贝数变异(CNV)约占孟德尔疾病中已报道致病突变的10%。然而,由于缺乏或未充分使用适当的检测方法,致病性CNV可能未被充分检测到。在本报告中,以一名患有马凡综合征(MFS)的患者的诊断历程为例,该患者携带一个此前未报道的32 kb缺失,我们强调了在当前的新一代测序(NGS)时代对孟德尔疾病中的CNV(>1 kb)进行检测的必要性和可行性。
