Interleukin 7 receptor (IL7R) is a gene that encodes a protein that functions as a receptor for interleukin 7. The protein also plays an important role in V(D)J recombination during lymphocyte development. Missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame insertions are observed in cancers such as endometrial cancer, lung cancer, and skin cancer.

IL7R is altered in 1.85% of all cancers with lung adenocarcinoma, cutaneous melanoma, colon adenocarcinoma, melanoma, and squamous cell lung carcinoma having the greatest prevalence of alterations [3].

The most common alterations in IL7R are IL7R Mutation (1.15%), IL7R Amplification (0.53%), IL7R I121* (0.04%), IL7R R206* (0.04%), and IL7R R267Gfs*28 (0.03%) [3].
