What is the official name of the SGCD gene?
The official name of this gene is “sarcoglycan, delta (35kDa dystrophin-associated glycoprotein).”
SGCD is the gene's official symbol. The SGCD 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 SGCD gene?
The SGCD gene provides instructions for making the delta component (subunit) of a group of proteins called the sarcoglycan protein complex. The sarcoglycan protein complex is located in the membrane surrounding muscle cells. It helps maintain the structure of muscle tissue by attaching (binding) to and stabilizing the dystrophin complex, which is made up of proteins called dystrophins and dystroglycans. The large dystrophin complex strengthens muscle fibers and protects them from injury as muscles tense (contract) and relax. The dystrophin complex acts as an anchor, connecting each muscle cell's structural framework (cytoskeleton) with the lattice of proteins and other molecules outside the cell (extracellular matrix).
How are changes in the SGCD gene related to health conditions?
Genetics Home Reference provides information about familial dilated cardiomyopathy, which is also associated with changes in the SGCD gene.
Where is the SGCD gene located?
Cytogenetic Location: 5q33-q34
Molecular Location on chromosome 5: base pairs 156,117,933 to 156,767,787
The SGCD gene is located on the long (q) arm of chromosome 5 between positions 33 and 34.
More precisely, the SGCD gene is located from base pair 156,117,933 to base pair 156,767,787 on chromosome 5.
