Nibrin (NBN) is a gene that encodes a protein that is a member of the MRE11/RAD50 double-strand break repair complex and is associated with Nijmegen breakage syndrome. Missense mutations, silent mutations, frameshift deletions, and nonsense mutations are observed in cancers such as colon cancer, stomach cancer, and endometrial cancer.

NBN is altered in 2.25% of all cancers with breast carcinoma, non-small cell lung carcinoma, colorectal adenocarcinoma, prostate cancer, and uterine corpus neoplasm having the greatest prevalence of alterations [3].

NBN GENIE Cases - Top Diseases

The most common alterations in NBN are NBN Mutation (1.21%), NBN Mutation (germline) (1.21%), NBN Amplification (0.98%), NBN Frameshift (0.22%), and NBN Frameshift (germline) (0.22%) [3].
