ALK is identified as a neuroblastoma predisposition gene. Germline mutations were found in ALK, a tryrosine kinase receptor, in affected families. In addition, somatic point mutations in ALK were found in sporadic cases of neuroblastomas. ALK mutations seem to lead to constitutive activation of its kinase activity and promote cell proliferation.
