What is the official name of the SACS gene?
The official name of this gene is “spastic ataxia of Charlevoix-Saguenay (sacsin).”
SACS is the gene's official symbol. The SACS 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 SACS gene?
The SACS gene provides instructions for producing a protein called sacsin. Sacsin is found in the brain, skin cells, muscles used for movement (skeletal muscles), and at low levels in the pancreas, but the specific function of the protein is unknown. Research suggests that sacsin may play a role in folding newly produced proteins into the proper 3-dimensional shape because it shares similar regions with other proteins that perform this function.
How are changes in the SACS gene related to health conditions?
Where is the SACS gene located?
Cytogenetic Location: 13q12
Molecular Location on chromosome 13: base pairs 23,902,961 to 24,007,866
The SACS gene is located on the long (q) arm of chromosome 13 at position 12.
More precisely, the SACS gene is located from base pair 23,902,961 to base pair 24,007,866 on chromosome 13.
