genetic markers

Recently identified genetic markers, called single nucleotide polymorphisms, that are associated with a small but statistically significant increase in the risk of breast cancer do not appear to substantially improve the accuracy of existing models that use clinical factors to predict an individual's risk, according to a new study in the Journal of the National Cancer Institute.

What is believed to be the largest study of its kind for the genetic roots of inflammatory bowel diseases has suggested new links to Crohn's disease as well as further evidence that some people of Jewish descent are more likely to develop it.

Scientists have identified genetic markers that allow the selection of eggs with the best chance of leading to successful pregnancy after in vitro fertilization.

This finding could both increase the success rate of single embryo transfer and diminish the risk of multiple pregnancies.

Researchers have uncovered clearly recognizable genetic alterations in tumors and tissue removed from patients with early-stage lung cancers that look like good predictors of which of these cancers are more likely to recur.
