地中海贫血是我国南方地区最常见的一种单基因遗传病,难以治愈且代价昂贵,通过穿刺术采集高风险胎儿的遗传物质进行产前基因诊断,防止重型患儿出生是国内外公认的首选措施。通过穿刺手术采集绒毛、羊水或脐带血而获取胎儿遗传物质进行产前诊断的有创性操作,可能造成胎儿损伤、流产或宫内感染等。自从母体血浆中发现存在胎儿DNA,以此胎儿遗传物质为检测靶标的无创产前诊断技术迅速发展。基于此类游离胎儿DNA的无创产前诊断更安全,且易于被受试者接受,也避免了获取胎儿遗传物质的创伤性操作导致的不必要风险。综述地中海贫血无创产前诊断的技术策略及其应用。
地中海貧血是我國南方地區最常見的一種單基因遺傳病,難以治愈且代價昂貴,通過穿刺術採集高風險胎兒的遺傳物質進行產前基因診斷,防止重型患兒齣生是國內外公認的首選措施。通過穿刺手術採集絨毛、羊水或臍帶血而穫取胎兒遺傳物質進行產前診斷的有創性操作,可能造成胎兒損傷、流產或宮內感染等。自從母體血漿中髮現存在胎兒DNA,以此胎兒遺傳物質為檢測靶標的無創產前診斷技術迅速髮展。基于此類遊離胎兒DNA的無創產前診斷更安全,且易于被受試者接受,也避免瞭穫取胎兒遺傳物質的創傷性操作導緻的不必要風險。綜述地中海貧血無創產前診斷的技術策略及其應用。

Thalassemiases are a group of the most common monogenic diseases in southern provinces of China. It is first choice method to prevent the birth of the affected children by prenatal genetic diagnosis in those high-risk couples through invasive sampling, which is widely accepted in the world. The risk of fetal injury, miscarriage or intrauterine infection may be caused by the invasive operation to collect villus, amniotic fluid, or cord blood for prenatal diagnosis. Since the cell-free fetal DNA (cff-DNA) was discovered in maternal plasma, the cff-DNA-based non-invasive prenatal diagnosis(NIPD) technology has been rapidly developed. The cff-DNA-based NIPD is safer and easily acceptable. In this review, noninvasive approaches in prenatal diagnosis of thalassemias were briefly discussed.
