Neurofibromin 1 (NF1) is a gene that codes for neurofibromin, a tumor suppressor protein (Genetics Home Reference 2014). NF1 suppresses the function of the Ras protein, which promotes cell growth and differentiation (Genetics Home Reference 2014PMID: 25026295). In cancer, the tumor suppression function of the gene is impaired, leading to conditions favorable for uncontrolled cell growth. NF1 mutations have been observed in multiple cancer types, including myelodysplastic syndromes.

In addition, NF1 syndrome is a germline condition resulting in predisposition to several types of cancer, in addition to other effects (PMID: 25026295). Cancer types associated with NF1 syndrome include glioma, melanoma, lung cancer, ovarian cancer, breast cancer, colorectal cancer, hematologic malignancies, and other cancers (PMID: 25026295).

NF1 is altered in 6.78% of all cancers with non-small cell lung carcinoma, breast carcinoma, melanoma, malignant glioma, and colorectal adenocarcinoma having the greatest prevalence of alterations [3].

NF1 GENIE Cases - Top Diseases

The most common alterations in NF1 are NF1 Mutation (6.15%), NF1 Mutation (germline) (6.15%), NF1 Nonsense (1.96%), NF1 Frameshift (1.39%), and NF1 Loss (0.36%) [3].
