Prof. Thierry Frébourg passed away on the 13th of March at the age of 60 years. An active member of ESHG, he has worked in the Scientific Program Committee and for several years as Section Editor of the European Journal of Human Genetics.

He was the founder of the clinical genetic services of Normandy and of a mixed University-Inserm research unit in Rouen. His clinical and scientific achievements and organization skills were appreciated nationwide, and he was assigned important roles in national scientific organizations.

One of his major scientific interests was in the TP53 related tumor predisposition syndrome. He had the goal to improve the treatment of patients affected with these tumors and cancer prevention in carriers at risk, and has closely collaborated with the French Li-Fraumeni Syndrome Association and with the European Reference Network on genetic tumour risk syndromes (GENTURIS). His last achievemnt in the field has been the publication of clinical guidelines, an essential step towards the standardization of care for subjects dealing with this rare condition.

The French and the European human genetics communities will greatly miss him, along with his enthusiasm for science and dedication to patients.
