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 2.14% of all cancers with non-small cell lung carcinoma, colorectal adenocarcinoma, melanoma, breast carcinoma, and uterine corpus neoplasm having the greatest prevalence of alterations [3].
