Trisomy 9 mosaic syndrome (T9M) is a rare condition characterized by multiorgan system involvement including craniofacial dysmorphisms, cardiac, genitourinary (GU), skeletal, and central nervous system (CNS) abnormalities. Although more than 100 cases have been reported in the literature, a ...
这是一个原本在外院诊断有高比例异常镶嵌型三染色体15(mosaic trisomy 15),同时并有疑似天使症候群(Angelman syndrome),即父源单亲二染色体15(paternal uniparental disomy15)即patUPD(15)的案例。焦虑的父母在妊娠25周时来到马偕纪念医院妇产科我的遗传咨询门诊就诊,寻求最后一缐希望,我也绞尽脑汁,努力不懈,排除原...
Up to date, 11 liveborn infants with trisomy 9 have been reported, which allows us to make a karyotype/phenotype correlation. Minimal clinical diagnostic criteria are defined, on the basis of which the presence of this syndrome can be suspected....

although these were frequently seen in BL cases in regions with multiple oncogenes or SMGs in BL. It is possible that accumulation of CNLOH of 1q arises due to trisomy rescue (mitotic loss of one copy of the duplicated chromosome), which counters the evolutionary accumulation of cells with ...
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. ...
Disomic homozygosity in 21-trisomic cells: a mechanism responsible for transient myeloproliferative syndrome In all nine patients, the leukemoid cells in TMS stage were largely or exclusively composed of trisomy or tetrasomy 21, an indication that the additional... K Abe,T Kajii,N Niikawa - 《...
Mosaic trisomy 21 accounts for 2–4% of Down's syndrome cases, which are distinct from complete trisomy in that the former can have less severe intellectual and developmental manifestations [24]. Mosaic Turner's syndrome, also known as mosaic X loss, also manifests in a less severe phenotype...
Mechanism A (upper sequence): The trisomy (A1) normalizes by anaphase lagging with chromothripsis of the supernumerary chromosome in the micronucleus (A2, right); a breakage event in the recipient chromosome (either in p or in q arm) with loss of the terminal portion (A3), the deleted ...
