Prof Eileen Treacy is a Consultant Metabolic Physician at Childrens University Hospital and the Mater Misericordiae University Hospital (since 2001), and is currently the National Clinical Lead for the HSE/RCPI Rare Diseases Clinical Programme (since December 2013).

After training in Paediatrics and Clinical Genetics in Canada, she subsequently trained in Biochemical Genetics in Paris and Melbourne (Australia) and was appointed first as Assistant Professor in Paediatrics and Medical Genetics (1994-1998) at Montreal Childrens Hospital/McGill University and Director of the McGill Charles Scriver Biochemical Genetics Unit (1996-2001), and then Associate Professor in Paediatrics and Medical Genetics at McGill University (1999- 2001).

 

Appointed as Clinical Professor of Inborn Errors of Metabolism (Paediatrics) at University of Dublin (TCD) since 2006.

Current trainer for RCPI Clinical Biochemical Genetics Training Programme at Mater Misericordiae University Hospital and Paediatrics Trainer. Registered as a specialist in Paediatrics and Clinical Genetics (Medicine).

 

Specific research interests in Rare Diseases, Inherited Metabolic Disorders and the treatment of Genetic Diseases.

Principal Investigator for Galactosaemia HRB-MRCG and HRB-HRA grants.

Co-Lead for European Galactosaemia Network (GalNet).

Member of UCD Academic Centre on Rare Diseases.

 

Currently the country coordinator (HSE) for the EC 2015-2018 Rare Diseases Joint Action Grant and National Validator for the Orphanet database/Lead for National Rare Diseases Office, (launched in June 2015). The National Rare Diseases Office coordinates the national Orphanet function, operates a helpline/information source for rare diseases for patients, families, researchers and the public and collaborates with rare disease research projects, dissemination of clinical practice guidelines and education in rare diseases: (website www.rarediseases.ie).

Research

Research Interests

My specific research interests are in the diagnosis and treatment of genetic/rare diseases.

 

Currently Principal Investigator for HRB-HRA POR grant: Galactosaemia, translating novel monitoring approaches into clinical practice, (Co-Investigator Dr Peter Doran). This study aims to further develop the measurement of the blood immunoglobulin glycoprotein, IgG as an improved clinical test for monitoring the galactose control in patients in parallel with the routine Galactose-1-phosphate blood test and dietary analysis; (2) to test in patient samples the abnormal functioning of a number of genes which we have identified which may be linked to the complications of cognitive impairment and fertility impairment in females; (3) collaborate with our European Galactosaemia research colleagues (Galactosaemia Network, EGN), to enter our Irish adult Galactosaemia patient data into the now developed European GalNet Registry.

 

Co-Lead of the Galactosaemia European Clinical/Research Network (GalNet), which involves 17 EC Member States.

Collaborating with the Dutch groups of Dr Annet Bosch and Dr. Estela Rubio-Gozalbo and the Swiss (Bern) Group, (Dr. Matthias Gautschi) for a number of studies in Galactosaemia.

 

National Lead for EC Joint Action in Rare Diseases, development of national Orphanet function (WP4) and collaboration with coding work package and epidemiological research in Rare Diseases.
