What is the official name of the NEFM gene?

The official name of this gene is “neurofilament, medium polypeptide.”

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

The NEFM gene provides the instructions to make the medium component (subunit) of neurofilaments. Neurofilaments, which are assembled from light, medium, and heavy subunits, are essential for normal nerve function. They form a structural framework that helps to define the shape and size of nerve cells. Cross-linking or bridging between neurofilaments maintains the diameter of the fiber, or axon, that extends from a nerve cell. Maintaining the proper axon diameter is essential for the conduction of nerve impulses.

Where is the NEFM gene located?

Cytogenetic Location: 8p21

Molecular Location on chromosome 8: base pairs 24,913,760 to 24,919,092

The NEFM gene is located on the short (p) arm of chromosome 8 at position 21.

The NEFM gene is located on the short (p) arm of chromosome 8 at position 21.

More precisely, the NEFM gene is located from base pair 24,913,760 to base pair 24,919,092 on chromosome 8.
