will having a brother who had diabetes stop me from being able to egg share?what constitutes a family history?

we need ivf to have children and our only option,due to money, is to egg share. we went to a consultation and on the face of things it's all good. but the questionaire we have to fill out asks if i have any family history of diabetes mellitus. my younger brother died as a result of cerebral eodema caused by ths condition, although we weren't aware he was diabetic until it was too late.no one else in our family has or is diabetic so will this class as a family history and will it stop me sharing my eggs?
