What is the official name of the MEGF8 gene?

The official name of this gene is “multiple EGF like domains 8.”

MEGF8 is the gene's official symbol. The MEGF8 gene is also known by other names, listed below.

What is the normal function of the MEGF8 gene?

The MEGF8 gene provides instructions for making a protein whose function is unclear. Based on its structure, the Megf8 protein may be involved in cell processes such as attaching cells to one another (cell adhesion) and helping proteins interact with each other. Researchers also suspect that the Megf8 protein plays a role in the normal shaping (patterning) of many parts of the body during embryonic development.

How are changes in the MEGF8 gene related to health conditions?

Carpenter syndrome - caused by mutations in the MEGF8 gene

At least six mutations in the MEGF8 gene have been found to cause Carpenter syndrome, a condition characterized by irregular skull formation, finger and toe abnormalities, and many other features. These mutations reduce or eliminate the function of the Megf8 protein. Researchers suspect that the amount of protein function that is retained may contribute to the variability in signs and symptoms. It is unclear how MEGF8 gene mutations cause Carpenter syndrome. The mutations likely interfere with normal patterning of many parts of the body, which contributes to the features of this disorder.

Where is the MEGF8 gene located?

Cytogenetic Location: 19q12

Molecular Location on chromosome 19: base pairs 42,325,609 to 42,378,769

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The MEGF8 gene is located on the long (q) arm of chromosome 19 at position 12.

The MEGF8 gene is located on the long (q) arm of chromosome 19 at position 12.

More precisely, the MEGF8 gene is located from base pair 42,325,609 to base pair 42,378,769 on chromosome 19.
