What is the official name of the ACVRL1 gene?
The official name of this gene is “activin A receptor type IL.”
ACVRL1 is the gene's official symbol. The ACVRL1 gene is also known by other names, listed below.

What is the normal function of the ACVRL1 gene?
The ACVRL1 gene provides instructions for making a protein called activin receptor-like kinase 1. This protein is found on the surface of cells, especially in the lining of developing arteries.
The ACVRL1 protein is a receptor. It acts as a "lock" waiting for a specific protein, called its ligand, to serve as the "key." In the case of the ACVRL1 protein, the ligand is called transforming growth factor beta. The interaction between these proteins plays a role in the development of blood vessels. In particular, this protein interaction is involved in the specialization of new blood vessels into arteries or veins.
How are changes in the ACVRL1 gene related to health conditions?
Genetics Home Reference provides information about pulmonary arterial hypertension, which is also associated with changes in the ACVRL1 gene.
Where is the ACVRL1 gene located?
Cytogenetic Location: 12q13.13
Molecular Location on chromosome 12: base pairs 51,906,913 to 51,923,361
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The ACVRL1 gene is located on the long (q) arm of chromosome 12 at position 13.13.
More precisely, the ACVRL1 gene is located from base pair 51,906,913 to base pair 51,923,361 on chromosome 12.
