摘要: The family history of cancer in children treated for a solid malignant tumour the Paediatric Oncology Department at Institute Gustave-Roussy, has been investigated. In order to determine role germline p53 mutations genetic predisposition childhood cancer, were sought individuals with least one relative (first- or second-degree first cousin) affected by any before 46 years age, multiple cancers. Screening mutation was possible 268 index cases among fulfilling selection criteria. Seventeen (6.3%) identified, which 13 inherited and four de novo. Using maximum likelihood methods that incorporate retrospective data correct ascertainment bias, lifetime risk carriers estimated be 73% males nearly 100% females high breast accounting difference. associated such is very no evidence low penetrance found. These are frequently but novo not rare.
