The Belgian Society of Human Genetics (BeSHG) was launched in March 2000 and aims at promoting human genetics in its wider sense, i.e. by supporting genetic research, improving exchanges between Belgium and foreign countries, organising scientific meetings, and enhancing collaboration between Belgian labs. During the 37th general annual meeting of the Belgian Haematology Society, a joint BeSHG-BHS session was organised. In this session, Karlijn Brekelmans (University Hospital Leuven, Leuven, Belgium) first discussed how genetic predisposition in haemato-oncological disorders can be detected, with a focus on technique, type of tissue that can be used and turn-around-time. Her talk was followed by a presentation from Esmé Waanders (Princess Maxima Centre, Utrecht, The Netherlands) discussing geentic predisposition in lymphoid malignancies.
