The risk of miscarriage due to amniocentesis was the same as the risk of having a baby with Down Syndrome. Amniocentesis is considered the gold standard, but it’s an invasive procedure with a 1/100 risk for miscarriage, the same risk for Downs. I quickly realized I would rather give birth to a baby with Downs than be responsible for a miscarriage. Fortunately, now there is a new, totally non-invasive procedure for genetic testing of Down Syndrome. It only requires the maternal blood sample (basic blood draw) to spot chromosomal abnormalities in the fetus. Scientists from Stanford University utilized fetal DNA fragments in the mother’s blood and read the fragments using DNA sequencing. Wom...

A new paper from Torres et al. shows that yeast with extra chromosomes actually grow slower, suggesting that the relationship between aneuploidy and cancer might be a bit more complex (if the phenomenon holds true on human cells). Then again, maybe yeast are just, well...yeast.

Geneticists love this......The So Called "Paradigm Shift"Back in 2005 this was done with Marfan's disease. It is an example I use to teach my students that what they may have learned is wrong. It is wrong because medical teaching is only built on science that has a very limited set of knowns and an immense set of unknowns.This paradigm shift is already in the making. The classical model of how a cancer develops is called the "two-hit" hypothesis. It states that in order to have uncontrolled growth of cells i.e. cancer, you need two hits to genes. Mostly you have to have at least 2 mutations. Sometimes you activate a gene by mutation and other times you may silence the genes. For the last 30 years the view of can...
