We sequenced the exomes of three unrelated individuals with hereditary PCC (cases) and identified mutations in MAX, the MYC associated factor X gene. Absence of MAX protein in the tumors and loss of heterozygosity caused by uniparental disomy supported the involvement of MAX alterations in the disease. A follow-up study of a selected series of 59 cases with PCC identified five additional MAX mutations and suggested an association with malignant outcome and preferential paternal transmission of MAX mutations. The involvement of the MYC-MAX-MXD1 network in the development and progression of neural crest cell tumors is further supported by the lack of functional MAX in rat PCC (PC12) cells and by the amplification of MYCN in neuroblastoma and suggests that loss of MAX function is correlated with metastatic potential.This work was supported in part by the Fondo de Investigaciones Sanitarias (projects PS09/00942 and P1080883 to A.C. and M.R., respectively), Mutua Madrilena (project AP2775/2008 to M.R.), FP7-Grant (ENS@T-CANCER; HEALTH-F2-2010-259735) and Innovation project INTRA-706-2 ISCIII CIBER-ER (Center for Biomedical Research on Rare Diseases).
