Bloom syndrome, RecQ helicase-like (BLM) is a gene that encodes a protein that possesses DNA helicases and functions in DNA-stimulated ATPase and ATP dependent DNA helicase processes. Missense mutations, nonsense mutations, silent mutations, frameshift deletions and insertions, and in-frame deletions are observed in cancers such as endometrial cancer, intestinal cancer, and stomach cancer.

BLM is altered in 2.05% of all cancers with colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, endometrial endometrioid adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].
