嵌合型16三体来自三体自救,因此有母源单亲二体的风险。 用绒毛膜采样检查出的16三体通常表现为胎盘局限性嵌合体(CPM),与宫内胎儿生长迟缓相关,但很少有其他畸形,即使16三题是局限于胎盘,但仍存在异常妊娠的潜在风险,如宫内胎儿生长迟缓导致宫内死亡、死产或早产(可能由于胎盘功能失调)。 羊膜穿刺术检查出的16三体...
Mosaic TrisomyMosaic FormThe sex ratio and X-chromosome inactivation were analyzed in placental tissues of human spontaneous abortuses with pure and mosaic forms of chromosome 16 trisomy. The sex ratio value was found to decrease with an increase in the share of cells with the trisomic karyotype,...

Finally, cytogenetic analysis showed the presence of non-mosaic X trisomy (65,XXX), an aneuploidy of sex chromosomes that is rarely detected in horses. This finding was also confirmed by molecular methods, including highly sensitive droplet digital PCR (ddPCR) and microsatellite markers genotyping. ...

嵌合型16三体(Mosaic trisomy 16) 01 16三体是在自发流产中最常见的三体,在所有做临床检查的孕妇中的发生率约为1.5%,占所有流产病例的7.5%。完全性16三体的妊娠仅能持续到最小胚胎发育.16三体来自母体减数分裂时的错误。嵌合型16三体来自三体自救,因此有母源单亲二体的风险。
Recent reports of premature separation of chromosome 16 bivalents during maternal meiosis I provide a novel mechanism for generation of this aneuploidy. Most, if not all, errors resulting in recognized mosaic and non-mosaic trisomy 16 pregnancies investigated using polymorphic DNA markers appear to ...
