What is the official name of the SGCE gene?
The official name of this gene is “sarcoglycan, epsilon.”
SGCE is the gene's official symbol. The SGCE gene is also known by other names, listed below.

What is the normal function of the SGCE gene?
The SGCE gene provides instructions for making a protein called epsilon (ε)-sarcoglycan, whose function is unknown. The ε-sarcoglycan protein is found within the cell membranes of the lungs, liver, kidneys, and spleen, but it is most abundant in nerve cells (neurons) in the brain and in muscle cells. Researchers suspect that in the brain the ε-sarcoglycan protein plays a role in the functioning of synapses, which are the connections between neurons where cell-to-cell communication occurs.
People inherit one copy of most genes from their mother and one copy from their father. Both copies are typically active, or "turned on," in cells. The SGCE gene, however, is active only when it is inherited from a person's father. This sort of parent-specific difference in gene activation is caused by a phenomenon called genomic imprinting.
How are changes in the SGCE gene related to health conditions?
Where is the SGCE gene located?
Cytogenetic Location: 7q21.3
Molecular Location on chromosome 7: base pairs 94,585,223 to 94,656,208
The SGCE gene is located on the long (q) arm of chromosome 7 at position 21.3.
More precisely, the SGCE gene is located from base pair 94,585,223 to base pair 94,656,208 on chromosome 7.
