Professor Patricia Munroe


Professor of Molecular Medicine

Centre: Clinical Pharmacology

Telephone: +44(0) 20 7882 3586


Patricia graduated with a B.Sc. in Biochemistry, and M.Sc. in Biotechnology from the National University Ireland, Galway. She then worked as a research technician at the Wellcome Trust Research Laboratories for six months before commencing a PhD in cardiovascular genetics at St Bartholomew’s Hospital. Patricia was awarded a PhD in Medicine in 1995, and following a post-doctoral fellowship at University College London (NIH funded), she joined the William Harvey Research Institute as a Lecturer in 1998. In 2007 she was appointed Professor of Molecular Medicine.

Prof Munroe’s research is focused on elucidating the genetic and molecular basis of hypertension and cardiac arrhythmias. She co-leads several international complex genetic disease consortia. Using meta-analysis of genome-wide association studies (GWAS) and large-scale candidate gene studies she has discovered over 30 genetic loci associated with hypertension during the past 3 years. She has also contributed data to several gene discoveries for cardiac arrhythmias (QRS, QT and RR) and other complex genetic traits.  Her work is funded by the British Heart Foundation, Medical Research Council, NIHR, The Wellcome Trust and Wellbeing of Women.

Determining the genetic and molecular basis of hypertension and cardiac arrhythmias
Hypertension is a multifactorial condition, affecting over one billion people worldwide. Recent estimates suggest that increased blood pressure contributes to 50% of coronary heart disease and 69% of stroke morbidity. Genes and lifestyle factors are important contributors, and via large-scale meta-analysis of genome-wide association studies many genetic loci are being discovered. Prolongation of the electrocardiographic QT interval is a risk factor for sudden cardiac death in the general population, and is a life-threatening complication of several medications. Genetic loci that contribute to variability of the QT interval have been discovered, also loci influencing heart rate, and QRS interval have been discovered, these ECG measures are indicators of the electrical function of the heart.

Professor Munroe’s current work is focused on further gene discovery for hypertension and ECG parameters influencing cardiovascular risk (QT, RR and QRS), and characterising the function of newly discovered genes.  We are:

  • Utilising bespoke genotyping arrays (cardiometabochip, IBC and Exome chip) in very large sample sizes via collaboration for further gene discovery.
  • Performing fine mapping studies to locate likely causative genetic variants, and functional studies of candidate genes using molecular biology techniques.
  • Developing a series of gene-targeted models for candidate genes derived from GWAS studies. Patricia is the Principal Investigator of the MRC Mouse Network Cardiovascular Trait Consortium.
  • Performing pharmacogenetic studies of hypertension, and working on a multicentre prospective observational study on post-mortem genetic testing to examine the incidence and inheritance patterns of lethal cardiac ion channelopathies in unexplained stillbirth.
