What is the official name of the SOD1 gene?
The official name of this gene is “superoxide dismutase 1, soluble.”
SOD1 is the gene's official symbol. The SOD1 gene is also known by other names, listed below.

What is the normal function of the SOD1 gene?
The SOD1 gene provides instructions for making an enzyme called superoxide dismutase, which is abundant in cells throughout the body. This enzyme attaches (binds) to molecules of copper and zinc to break down toxic, charged oxygen molecules called superoxide radicals. Superoxide radicals can damage cells if too many accumulate within cells. Superoxide radicals are byproducts of normal cell processes, particularly energy-producing reactions, and must be broken down regularly.
How are changes in the SOD1 gene related to health conditions?
Where is the SOD1 gene located?
Cytogenetic Location: 21q22.11
Molecular Location on chromosome 21: base pairs 31,659,622 to 31,668,931

The SOD1 gene is located on the long (q) arm of chromosome 21 at position 22.11.
More precisely, the SOD1 gene is located from base pair 31,659,622 to base pair 31,668,931 on chromosome 21.
