What is the normal function of the DHH gene?
The DHH gene provides instructions for making a member of the hedgehog protein family. Hedgehog proteins are important for early development in many parts of the body. The protein produced from the DHH gene is believed to be involved in male sexual development and in the formation of the perineurium, the protective membrane around each bundle of fibers within a nerve.
How are changes in the DHH gene related to health conditions?
Where is the DHH gene located?
Cytogenetic Location: 12q13.1
Molecular Location on chromosome 12: base pairs 49,089,421 to 49,094,819
