Trisomy 9 allows near normal life expectancy although it also involves developmental and mental retardation. Individuals with trisomy 21 (Down's syndrome) also reach adulthood but remain mentally subnormal. Trisomy 22 may exist in mosaic form and the afflicted individuals are retarded in growth and ...
Life expectancy can be normal in trisomy 8 mosaic individuals. • Trisomy 9 mosaicism results from a meiotic error. • Common US findings in trisomy 9 mosaicism include IUGR and amniotic fluid abnormalities, craniofacial, cardiac, skeletal, and urinary findings. • Individuals with mosaic trisom...
(P10), all three lines of 18T-iPSCs analyzed had a full trisomy 18 karyotype. At passage 14, iPSCs were found to be mosaic, comprising of both diploid and trisomic cells. At the late passage (P20), all iPSCs had converted to diploid cells (Figure 5c). In addition, results of our...
It is characterized by the presence of an extra copy of chromosome 21 and can result from various genetic abnormalities such as mater‑ nal non-disjunction, mosaic karyotype, Robertsonian translocation, or partial duplication of the critical region of chromosome 21(Hoeffer et al. 2007; Anton...

Improved long-term survival has been associated with partial or mosaic trisomies compared to children with full trisomy, albeit cytogenetic mosaics and Robertsonian translocations are considerably less prevalent across populations. In a British study, a 1-year survival rate of 70% was found for childre...
