Alteration of a gene causes neuroblastoma

Olivier Delattre's team (Inserm Unit 830 "Genetics and Biology of Cancer") of the Institut Curie reveal in an article in the 16 October issue of Nature that alteration of the ALK gene is closely associated with the most frequent solid extracerebral tumor in children-neuroblastoma. By studying the familial forms of this tumor, the researchers also conclude that ALK is a gene that predisposes to neuroblastoma.
