IKAROS family zinc finger 1 (Ikaros) (IKZF1) is a gene that encodes a transcription factor protein that functions in chromatin remodeling and the regulation of lymphocyte differentiation. Fusions, missense mutations, nonsense mutations, silent mutations, whole gene deletions, and frameshift deletions and insertions are observed in cancers such as hematopoietic and lymphoid cancers, lung cancer, and skin cancer.

IKZF1 is altered in 1.96% of all cancers with lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, breast invasive ductal carcinoma, and melanoma having the greatest prevalence of alterations [3].

IKZF1 GENIE Cases - Top Diseases

The most common alterations in IKZF1 are IKZF1 Mutation (2.01%), IKZF1 Amplification (0.22%), IKZF1 Loss (0.13%), IKZF1 Nonsense (0.12%), and IKZF1 Frameshift (0.06%) [3].
