18, and 21 survive to term and are seen in the population. Trisomy for sex chromosomes, such as XXX orXXY, has fewer deleterious effects on development; most of these trisomies result in term live births. The p
In the case of trisomy 13 or 18, the data clearly show that the belief that survival beyond the neonatal period is impossible, or nearly impossible, is mistaken. We do not know how many would survive if maximal efforts were made for each child, but we know without doubt that some of ...
purpose, and functions and how they are relevant to us in T21RS. Fisher went on to consider what the future may look like for research into trisomy 21. She then presented some recent and largely unpublished results produced jointly by her ...
If triploids can, and usually do, have two active X's and if the XIST repressor was encoded by a single autosomal locus, then trisomies, with three copies of the relevant gene, might also have two active X's. We realized that not all cells trisomic for the putative trans-acting factor...
Given the rarity of children with Trisomy 13 surviving to adulthood, the clinical complications and expected pathologies in such patients as they age are not well known. Increased incidence of malignancy in patients with constitutional Trisomy, including Trisomy 13, 18, and 21, has been described ...

trisomy 18; Edwards syndrome; aneuploidy; Dandy-Walker; long-term survival1. Introduction Trisomy 18 (T18), or Edwards syndrome (ES), is a genetic disease resulting from an additional 18 chromosome, characterized by a broad clinical spectrum, poor prognosis and low life expectancy. The live ...
