The RARA gene is a crucial part of the human genome, located on chromosome 17. It encodes a protein that is a member of the nuclear receptor superfamily, which plays a significant role in regulating gene expression. This gene is particularly important in the development and function of the retinoic acid signaling pathway, which is essential for normal cellular processes. Mutations or alterations in the RARA gene can lead to various health issues, including certain types of cancer, such as acute promyelocytic leukemia (APL). In APL, the RARA gene often fuses with the PML gene, creating a new protein that disrupts normal cell function and promotes cancer development. Understanding the RARA gene is vital for developing targeted therapies for these conditions.
