MITF (Melanocyte Inducing Transcription Factor): MITF is a key regulator that reflects the role of MITF in the development and function of melanocytes, the cells responsible for pigment production. It is essential for normal pigmentation, and mutations in MITF can lead to pigmentary disorders and increase the risk of melanoma, a type of skin cancer. MITF also contributes to the development of certain retinal cells and is implicated in Waardenburg syndrome.
