What is the official name of the ENG gene?

The official name of this gene is “endoglin.”

ENG is the gene's official symbol. The ENG 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 ENG gene?

The ENG gene provides instructions for making a protein called endoglin. This protein is found on the surface of cells, especially in the lining of developing arteries. It forms a complex with growth factors and other proteins involved in the development of blood vessels. In particular, this complex is involved in the specialization of new blood vessels into arteries or veins.

Does the ENG gene share characteristics with other genes?

The ENG gene belongs to a family of genes called CD (CD molecules).

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 ENG gene related to health conditions?

hereditary hemorrhagic telangiectasia - caused by mutations in the ENG gene

Dozens of mutations in the ENG gene have been found to cause hereditary hemorrhagic telangiectasia type 1. Many ENG gene mutations substitute one protein building block (amino acid) for another amino acid in the endoglin protein, which impairs the protein's function. Other mutations prevent production of the endoglin protein or result in an abnormally small protein that cannot function. The shortage of functional endoglin appears to interfere with the development of boundaries between arteries and veins, resulting in the signs and symptoms of hereditary hemorrhagic telangiectasia type 1.

Where is the ENG gene located?

Cytogenetic Location: 9q34.11

Molecular Location on chromosome 9: base pairs 130,577,290 to 130,617,046

The ENG gene is located on the long (q) arm of chromosome 9 at position 34.11.

The ENG gene is located on the long (q) arm of chromosome 9 at position 34.11.

More precisely, the ENG gene is located from base pair 130,577,290 to base pair 130,617,046 on chromosome 9.
