研究目的:

有报道表明将近60%的严重产后单基因疾病是显性疾病,其中大多数是由新发突变(父母正常但子代发生突变)引起的,且怀孕时父亲年龄增长是新发突变发生率增高的危险因素。新发突变的发病率相对较高,但胎儿宫内不一定出现超声异常,且在临床上缺乏有效的早期筛查方法。目前无创胎儿染色体非整倍体产前检测(NIPT)只能检测胎儿21号染色体三体型综合征、18号染色体三体型综合征、13号染色体三体型综合征三种类型的综合征,扩展的无创产前检测(NIPT-plus)也仅将筛查范围扩大到100种染色体疾病。本研究针对30种常见致残、致愚、致死性单基因病(综合发病率约为1-2/1000)进行无创产前筛查,可作为常见染色体疾病无创产前筛查的良好补充,实现一管血即可完成严重常见染色体疾病和单基因病的联合筛查目标。  

Objectives of Study:

It has been reported that nearly 60% of severe postpartum monogenic diseases are dominant diseases, most of which are caused by new mutations (normal parents but mutations in the offspring), and the increase in the fathers age during pregnancy is an increase in the incidence of new mutations risk factors. The incidence of new mutations is relatively high, but ultrasound may not be abnormal in the fetus, and there is a lack of clinically effective early screening methods. At present, non-invasive fetal chromosome aneuploidy prenatal testing (NIPT) can only detect three types of fetal chromosome trisomy syndrome, chromosome 18 trisomy syndrome, and chromosome 13 trisomy syndrome, extended Non-invasive prenatal testing (NIPT-plus) also only expands the scope of screening to 100 chromosomal diseases. In this study, non-invasive prenatal screening for 30 common disabling, folly, and fatal single-gene diseases (combined incidence rate is about 1-2/1000) is used as a good supplement to non-invasive prenatal screening for common chromosomal diseases. A single tube of blood can complete the combined screening target for serious common chromosomal diseases and monogenic diseases.

随机方法(请说明由何人用什么方法产生随机序列):

不对入选病例进行随机分组。所有入选病例尽可能通过有创取得胎儿的羊水或绒毛或脐带血,将由此获得的DNA进行本项目关注的30余个显性单基因的二代测序及一代测序验证,作为诊断的金标准。除此之外,获取符合入组条件病例的孕妇外周血提取血浆内的胎儿游离DNA进行本项目内关注的30余个显性单基因的无创检测,最后与金标准进行比较。

Randomization Procedure (please state who generates the random number sequence and by what method):

The selected cases will not be randomized. All the selected cases were able to obtain fetal amniotic fluid or villi or umbilical cord blood through invasive methods, and the DNA obtained therefrom was verified by second-generation sequencing and first-generation sequencing of more than 30 dominant single genes
