What is the official name of the AMH gene?

The official name of this gene is “anti-Mullerian hormone.”

AMH is the gene's official symbol. The AMH gene is also known by other names, listed below.

What is the normal function of the AMH gene?

The AMH gene provides instructions for making a protein that is involved in male sex differentiation. During development of male fetuses, the AMH protein is produced and released (secreted) by cells of the testes. The secreted protein attaches (binds) to its receptor, which is found on the surface of Müllerian duct cells. The Müllerian duct, found in both male and female fetuses, is the precursor to the female reproductive organs. Binding of the AMH protein to its receptor induces self-destruction (apoptosis) of the Müllerian duct cells. As a result, the Müllerian duct breaks down (regresses) in males. In females, who do not produce the AMH protein during fetal development, the Müllerian duct becomes the uterus and fallopian tubes.

Does the AMH gene share characteristics with other genes?

The AMH gene belongs to a family of genes called endogenous ligands (endogenous ligands).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? ( in the Handbook.

How are changes in the AMH gene related to health conditions?

persistent Müllerian duct syndrome - caused by mutations in the AMH gene

Persistent Müllerian duct syndrome type 1, a disorder of sexual development that affects males, is caused by mutations in the AMH gene. Males with this condition have female reproductive organs in addition to normal male reproductive organs. At least 38 mutations in the AMH gene have been identified in people with persistent Müllerian duct syndrome type 1. Most mutations change single protein building blocks (amino acids) in the AMH protein. Other mutations result in a premature stop signal that leads to an abnormally short protein. Still other mutations delete regions of DNA from the AMH gene, which changes the instructions for the protein.

The mutated AMH protein cannot be released from the cells of the testes or cannot bind to the receptor on the Müllerian duct cells. As a result, the Müllerian duct cells never receive the signal for apoptosis. The Müllerian duct persists and becomes a uterus and fallopian tubes. Because the AMH protein is not involved in the formation of male reproductive organs, affected males also have male reproductive organs.

Where is the AMH gene located?

Cytogenetic Location: 19p13.3

Molecular Location on chromosome 19: base pairs 2,249,114 to 2,252,073

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The AMH gene is located on the short (p) arm of chromosome 19 at position 13.3.

The AMH gene is located on the short (p) arm of chromosome 19 at position 13.3.

More precisely, the AMH gene is located from base pair 2,249,114 to base pair 2,252,073 on chromosome 19.
