Cancer Predisposition Syndromes (CPS), caused by germline mutations in cancer predisposition genes (CPG) are heritable disorders associated with an increased risk of developing certain types of cancer.~Knowledge of CPG will advance the understanding of tumorigenesis, improve patient care, and facilitate genetic counselling of patients and families. But the prevalence of CPS in Australian children with cancer and the psychosocial impact of germline sequencing to identify CPG have not been studied.~The clinical benefit of family-based WGS in every new child with cancer compared with conventional predictive factors is currently unknown. By testing every child with newly diagnosed cancer the aim is to determine the utility of this approach and its impact on participants and families.~The principal objective of the proposed multicentre prospective study is establish the clinical benefit and utility of family-based WGS to identify underlying CPS in every newly diagnosed child with cancer.
