NBN gene is considered as one of the low-to-moderate cancer susceptibility gene. At least 4 germline NBN mutations have been found in several malignancies in adults. In our studies, we observed the high incidence of germline mutation I171V of NBN gene in breast, colorectal, larynx cancer, and in multiple primary tumors. In this study, we would like to answer the question whether I171V germline mutation of NBN gene may constitute risk factor for solid tumors in children. The frequency of this mutation has been analyzed in patients with neuroblastoma (n=66), Wilms tumor (n=54), medulloblastoma (n=57), and rhabdomyosarcoma (n=82) hospitalized in Pediatric Oncology, Hematology and Bone Marrow Transplantation Department in the years between 1987 and 2010. About 2947 anonymous blood samples collected on Guthrie cards drawn from the newborn screening program of the Wielkopolska region have been used as controls. All the patients and controls came from the same geographical region. I171V mutation of the NBN gene has been observed in 5 controls. Among children with solid tumors only in 1 child with medulloblastoma I171V variant has been found. In conclusion, I171V germline mutation in contrary to adults cannot be considered as a risk factor for children malignancies. However, owing to low number of patients with solid tumors the possibility of a Type II error may exist.
