Chromosome abnormalities in pregnancy; meiotic recombination
Over 50% of all human pregnancy loss is due to chromosome imbalance in the fetus, making chromosome abnormalities the leading cause of reproductive failure. One of the primary aims of my laboratory is the use of cytogenetic and molecular techniques to study the origin and etiology of human chromosome abnormalities, with the aim being to uncover basic mechanisms responsible for the errors. Additionally, because of the importance of abnormal meiotic recombination to the genesis of human trisomies, we have recently initiated a series of studies to examine factors responsible for “setting” recombination levels in mammalian males and females.
