The desert hedgehog gene is a key gene to the human reproductive system. It plays a vital role in the development of important sexual organs. Along with the other hedgehog proteins, the hedgehog protein family and signaling pathway are also important to the overall development of many parts and systems of the human body. Each protein within the family has its own role to play in overall expression of cells and growth. There are a total of three proteins within the family; the Indian hedgehog (IHH), the sonic hedgehog (SHH), and the desert hedgehog (DHH) gene. The term hedgehog refers to the terminal domains within the genes of this family. The C terminal of the gene also known as the “hog” domain and the N terminal of the gene known as the
