As a Professor of Genomic Medicine and Clinical Geneticist, my research is translational and spans clinical phenotyping and genotyping, diagnostic methods and molecular mechanisms. The clinic provides a rich resource for genetics and genomics research finding new causes for rare disorders. Improving diagnostic analyses through genomics and transcriptomics is an exciting opportunity at the University of Southampton.  

Prof. Diana Baralle was appointed to a personal chair at the University of Southampton Faculty of Medicine in 2016 and  awarded the prestigious NIHR Research Professorship in 2017. Having graduated in medicine from the University of London, she trained first in Paediatrics and then Clinical Genetics. She completed her MD and research training fellowship in the Department of Pathology, Cambridge University working on the molecular pathology of NF1. She held an academic position in Cambridge before her current appointment in Southampton and combines her clinical work with her research interests.

Dr Baralle’s leads a group that investigates the role of RNA and splicing in genetic disease. Complimentary to this is research into new methods for genetic diagnostic testing, diagnostic RNA testing and causes of dysmorphology syndromes. She is also clinical specialty lead for Genetics for the Wessex CLRN. Her research is based within the Faculty of Medicine Human Development and Health Department. Her group comprises both clinical and non-clinical scientists and students.

She is a consultant in Clinical Genetics at University Hospital Southampton NHS Foundation Trust, and has general genetics clinics as well as a specialist oculogenetics clinic.

Research interests

Translational genomics and transcriptomics

Through NIHR funding we are developing novel diagnostic RNA pathways, biomarkers, techniques and guidelines to maximise the clinical utility of genome sequencing.

One in seventeen people are born with or develop a rare disease during their lifetime and at least 80% of rare diseases have an identified genetic component; 50% of new cases are identified in children. One in three people will get cancer and genomics transforms pathology to find the right treatment to the right patient. Novel disease genes are being discovered at an unprecedented rate.

The in-depth study of RNA from patients is a powerful tool complementing traditional and novel genomics-based medical diagnostics. Crucially, RNA provides information missed by standard methods of analysis.

The role of RNA processing defects in genetic disease

Abnormalities of pre-mRNA splicing represent an important mechanism by which gene mutations cause disease. Genomic pathology data reveals that we still have much to learn about the basic mechanisms that underlie the complex and exciting pre-mRNA splicing process. To this end, we study a variety of disorders, augmenting our knowledge of splicing and ultimately look to develop potential future interventional genetic therapies.

Functional Genomics

Through Dr Douglas within my team and in collaboration with others we have set up the Wessex Data-Integrated Analysis of Monogenic Disease (DIAMonD) Project, a wide-ranging translational and clinically applied research study that seeks to utilise clinical, laboratory and publically available data to better understand genetic disorders and to allow the more accurate diagnosis of patients affected by such conditions.  It is an overarching project that incorporates functional genomics, data analysis, laboratory investigations and experiments and also the interpretation of genetic variants.


Through my Clinical genetics practice and collaboration both nationally and internationally I investigate the cause and phenotype in dysmorphic syndromes. In particular, I have a special interest in two rare disorders: PURA syndrome and TRIO syndrome and work closely with the PURA patient foundation.

CRN Genetics

As clinical specialty lead for Genetics in Wessex I lead a team that recruits to CRN studies. A list of the Genetics studies can be found on the BSGM and the NIHR websites.
