title: New directions in cytogenetic and molecular testing of the neonate.
abstract: The development of new diagnostic, and hence therapeutic possibilities, has brought the realization that genetic disease is now an integral part of medical practice. Advances in cytogenetic and molecular testing have drastically improved the ability to diagnose with certainty many previously unrecognized conditions. However, this advance in technology does not come without new questions. New tests are not always the most cost effective ones, some have significant diagnostic limitations, and others raise valid ethical issues surrounding the testing of minors. A working understanding of new advances in genetic diagnosis as well as their inherent limitations is crucial for the contemporary practitioner.
