摘要
随着高敏感性遗传学检测技术在产前诊断领域的广泛应用,产前染色体嵌合体的检出越来越普遍,其诊断标准、遗传咨询原则和临床处理方案在不同单位之间可能存在不同程度的差异。这不仅给实验室、产前咨询医师或胎儿医学医师的诊疗工作带来了挑战,而且也给孕妇及其亲属造成了焦虑与困扰。鉴于此,本组专家就染色体嵌合体的产前遗传学诊断与遗传咨询达成共识,以期建立标准化的诊疗规范,从而更好地指导临床诊疗工作。
With the extensive application of highly sensitive genetic techniques in the field of prenatal diagnosis,prenatal chromosomal mosaicisms including true fetal mosaicisms and confined placental mosaicisms are frequently identified in clinical settings,and the diagnostic criteria and principle of genetic counseling and clinical management for such cases may vary significantly among healthcare centers across the country.This not only has brought challenges to laboratory technician,genetic counselor and fetal medicine doctor,but can also cause confusion and anxiety of the pregnant woman and their family members.In this regard,we have formulated a consensus over the prenatal diagnosis and genetic counseling for chromosomal mosaicisms with the aim to promote more accurate and rational evaluation for fetal chromosomal mosaicisms in prenatal clinics.
