Introduction: Down syndrome screening has become an important part of antenatal care and is performed for pregnant women worldwide. In this study, 45 statistically accurate cases of false negatives in the first trimester screening tests have been examined statistically, so that by paying attention to some criteria, we can find out how many of these cases can be detected and how much each criter...
Animal models are extensively used in genetics, neuroscience and biomedical research. Recent studies illustrate the usefulness and the challenges of research utilising genetically engineered mice to explore the developmental biology of Down syndrome. These studies highlight many of the issues at the centre of what we understand about Down syndrome, and may one day point to useful ways to improv...

down's syndrome (ds) is the most common chromosomal abnormality in human. subjects with ds are known to be peridisposed to develop leukemia. the molecular basis of the association between ds and leukemia is unknown. the unscheduled dna synthesis (uds) test measure the ability of dna-repair in mammalian cells after excision of a stretch of dna containing the region of damage induced by chem...
We report an extremely rare case of Turner syndrome mosaicism in a 30-year-old woman. At least 100 metaphases were observed and analyzed through GTG banding with over 550 band resolutions observed. G-banded chromosome analysis revealed a mosaic female karyotype involving 3 different cell lines. One cell line (90% of the analyzed metaphases) presented monosomy X, while 6% of the cells showed tri...
Understanding attitudes of the public toward people with Down syndrome is important because negative attitudes might create barriers to social integration, which can affect their success and quality of life. We used data from two 2008 U.S. surveys (HealthStyles(c) survey of adults 18 years or older and YouthStyles(c) survey of youth ages 9-18) that asked about attitudes toward people with Down ...
