Overview
High resolution array analysis has been introduced in the field of prenatal diagnosis, especially for pregnancies with fetuses at risk for a chromosomal aberration based on ultrasound findings. Results obtained with array analysis can range from normal to clearly pathogenic and explaining the ultrasound anomalies. This presentation, however, will focus on results of which the clinical significance is unclear or uncertain.
Can CMA replace standard karyotyping?
Speaker BIO:
Dr. Francesco Fiorentino, is founder and CEO of GENOMA, a private molecular genetics laboratory which is now one of the world's largest, fully integrated, specialized provider of genetics services. Dr. Fiorentino is a molecular biologist, internationally recognized in the fields of reproductive genetics, for its leadership in Preimplantation Genetic Diagnosis (PGD) and for its pioneering work in infertility and genetics. He is also well known as one of the pioneers in the creation of the specialties of reproductive and prenatal genetics and was the impetus behind development of many important concepts and techniques that have become standard in these important fields.
Dr. Fiorentino began his career at the the Italian Police Department- Forensic Science Service (FSS), Rome - Italy, where he spent 3 years performing research and investigation on forensic genetics, coordinating the DNA analysis unit.
Dr. Fiorentino later established GENOMA Laboratory, where he initiated a highly successful preimplantation genetic diagnosis (PGD) program, which has grown exponentially since its inception becoming one of the worldwide leaders in both in quality and volume.
Dr. Fiorentino is actively involved in PGD and the study of human oocytes and embryos, since almost two decades. His laboratory has a strong translational emphasis and is actively involved in the development of new techniques for improving the success rates of in vitro fertilization (IVF) treatment. Dr. Fiorentino’s research also aims to create novel PGD methods that are more comprehensive and more reliable than those in current use.
During his PGD activity, Dr. Fiorentino conceived and implemented the innovation of using Minisequencing technique for mutation detection on single cells, a procedure that is now widely used by most of the PGD centers.
Dr. Fiorentino and his group began clinical trials of array-comparative genomic hybridization (arrayCGH), a comprehensive chromosome screening method, aimed at revealing which of the embryos produced during an in vitro fertilisation (IVF) treatment cycle has the greatest potential for producing a child. The clinical application of this approach has been associated with some of the highest IVF pregnancy rates ever recorded and is now widely practiced worldwide.
Recently, he was responsible for the development and the first clinical application of Next Generation Sequencing (NGS) technology in Preimplantation Genetic Screening (PGS), for reliably screening the entire chromosome complement in embryos.
Dr. Fiorentino research work has been noted for its novelty and has frequently produced advances that have been translated from the research lab into clinical practice. His research has led to the publication of more than 40 peer-review papers and book chapters and has generated a great deal of media interest.
Overview
A significant number of important and large prospective clinical trials on chromosome microarray analysis(CMA) for prenatal testing that have been published recently. The combined data from these studies clearly indicate that, compared with conventional karyotyping, the use of CMA in prenatal diagnosis improves substantially the detection rate of pathogenic chromosomal abnormalities. The higher detection rate by CMA is not confined to cases with abnormal ultrasound findings. The results of the above studies demonstrate the improved diagnostic ability of CMA to detect clinically relevant abnormalities and the utility of bringing CMA into routine prenatal practice as a primary diagnostic tool for a number of other indications.
Findings to date provide substantial evidence for the introduction of CMA as a first-line test for all pregnant women undergoing invasive prenatal testing, regardless of risk factors, with the ultimate goal of improved prenatal diagnosis and a lower risk of giving birth to a chromosomal abnormal neonate.

Vincenzo Cirigliano is based in Barcelona where he heads the Molecular Genetics dept of General Lab-Labco the largest network of clinical laboratories in Spain. Graduated at the University of Naples, he was trained in Genetics at the National Research Council before moving to the Obs&Gyn dept. of University College London. He obtained his PhD cum laude in molecular and cell Biology at the “Universitat Autonoma of Barcelona” where he is now actively involved in Master and PhD programs as well as research projects of basic and clinical cytogenetics.
His main focus is reproductive genetics- prenatal diagnosis, including non invasive prenatal diagnosis using free fetal nucleic acids in maternal plasma and fetal cells from the endorcervical canal. He pioneered development and large scale clinical application of rapid prenatal detection of aneuploidies by QF-PCR and he is experienced in the development and clinical implementation of new molecular diagnostic assays.

Overview
Newly developed non-invasive prenatal diagnosis (NIPD) tests based on analysis of cell free fetal DNA are allowing couples at risk of some single gene disorders to have prenatal diagnosis using a maternal blood test from nine weeks in pregnancy.
In the United Kingdom (UK), NIPD for autosomal dominant conditions such as achondroplasia, thanatophoric dysplasia, and Apert syndrome are now in routine clinical service, as is NIPD for paternal exclusion of cystic fibrosis. NIPD for recessively inherited single gene disorders is more complex as high background level of maternal mutant alleles must be taken into account. Currently the majority of these tests are done using next generation sequencing which is now lending itself to NIPD for recessive disorders such as congenital adrenal hyperplasia. The process by which we have developed these tests and gained approval for use in the UK National Health Service will be described, data relating to patients experience of NIPD will be presented and issues relating to implementation of a prenatal diagnostic service based on NIPD will be discussed.

Overview
As primary screening to all patients:
The introduction of non-invasive prenatal testing (NIPT) via cell-free DNA analysis has led to marked increases in the accuracy of screening for Down syndrome and other chromosome conditions compared to standard serum-based screening protocols. Studies have demonstrated sensitivity of >99% and an extremely low FPR (0.1%) for trisomy 21. While early clinical validation studies were focused on enriched patient groups with high risk of aneuploidy, recent studies have demonstrated this same performance in the general screening population. As such, careful consideration is appropriately being given to implementation of this technology both on an individual provider level and as part of a nationwide or public prenatal screening program. Rationale for the offering of NIPT as a first line screening to any woman opting for aneuploidy risk assessment will be discussed.
As contingent screening in very high and intermediate risk patients:
The conventional Combined test has model predicted 85% Down syndrome detection rate for a 5% false-positive rate whilst maternal plasma cell-free (cf)DNA testing has rates of 99.3% and less than 0.14% respectively. However, current costs preclude replacing conventional screening by routine cfDNA screening in public health programs. Contingent cfDNA screening is an affordable compromise protocol restricting cfDNA to those with very high and/or intermediate Combined test risks with or without additional markers. The protocol also helps overcome the relatively high cfDNA test failure rate and retains detection of other disorders (eg NT and cardiac abnormalities) or pregnancy conditions (eg PAPP-A and pre-eclampsia).

Overview
In many countries, non-invasive prenatal testing (NIPT) became available to pregnant women in 2012 or 2013. At first, since only a few laboratories in the USA, China and Germany were able to provide this service, obstetricians after counseling took blood samples and shipped them to these labs. Patients paid the, at first, high costs themselves. In 2014, non-commercial (university) laboratories were able to perform NIPT themselves. National screening programs emerged incorporating NITP, and prices dropped conside
