What is the official name of the DBH gene?
The official name of this gene is “dopamine beta-hydroxylase (dopamine beta-monooxygenase).”
DBH is the gene's official symbol. The DBH gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the DBH gene?
The DBH gene provides instructions for producing the enzyme dopamine beta (β)-hydroxylase. This enzyme converts dopamine to norepinephrine, both of which are chemical messengers (neurotransmitters) that transmit signals between nerve cells. Norepinephrine plays an important role in the autonomic nervous system, which controls involuntary body processes such as the regulation of blood pressure and body temperature.
How are changes in the DBH gene related to health conditions?
Where is the DBH gene located?
Cytogenetic Location: 9q34
Molecular Location on chromosome 9: base pairs 133,636,363 to 133,659,344
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The DBH gene is located on the long (q) arm of chromosome 9 at position 34.
More precisely, the DBH gene is located from base pair 133,636,363 to base pair 133,659,344 on chromosome 9.
