The DHH gene is located on the long arm of at position 12q13.2 and consists of three exons, producing a precursor protein of 396 that undergoes autocatalytic cleavage and modification to generate the active signaling form. In mammals, DHH is predominantly expressed in the gonads, where it is crucial for the development and maintenance of the ; specifically, it supports the differentiation of Sertoli cells in the testes, the formation of Leydig cells, and the integrity of the blood-testis barrier during . Mutations in Dhh are associated with several rare disorders, most notably 46,XY gonadal dysgenesis (both partial and complete forms), which leads to underdeveloped or absent testes and infertility in genetic males, as well as minifascicular neuropathy characterized by abnormal nerve structure.

Research into DHH signaling has also implicated it in peripheral nerve myelination and potential therapeutic targets for developmental disorders and cancers involving hedgehog pathway dysregulation.
