Micropthalmia-associated transcription factor (MITF) is a gene that encodes a transcription factor protein that functions in the differentiation and development of melanocytes retinal pigment epithelium. The protein also regulates the pigment cell-specific transcription of melanogenesis enzyme genes. Missense mutations, nonsense mutations, silent mutations, and frameshift deletions and insertions are observed in cancers such as hematopoietic and lymphoid cancers, intestinal cancer, and lung cancer.
MITF is altered in 1.10% of all cancers with colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, endometrial endometrioid adenocarcinoma, and melanoma having the greatest prevalence of alterations .
The most common alterations in MITF are MITF Amplification (0.15%), MITF Loss (0.10%), MITF R60C (0.02%), MITF A384T (0.02%), and MITF R330H (0.02%) .
