Lyn Chitty, Professor of Genetics and Fetal Medicine at the UCL Great Ormond Street Institute of Child Health and Great Ormond Street NHS Foundation Trust, has published extensively on prenatal diagnosis and ultrasound screening of fetal abnormalities. Recently her main research interest has been around the use of circulating cell free DNA. She led an NIHR programme -Rapid Accurate Prenatal non-Invasive Diagnosis (RAPID) – which resulted in clinical implementation of NIPD for monogenic diseases. She continues to work on the implementation of new molecular techniques to improve prenatal diagnosis through implementation of rapid exome sequencing and extended development of NIPD. Her work includes developing methods to ensure informed parental consent for these more complex tests. She is an NIHR Senior Investigator, Editor-in-Chief of the journal Prenatal Diagnosis, President of the International Society of Prenatal Diagnosis, Deputy Director of the GOSH NIHR Biomedical Research Centre and Medical Director for the London North Genomic Lab Hub, one of seven delivering genomic testing for England.
