What is the official name of the FKRP gene?
The official name of this gene is “fukutin related protein.”
FKRP is the gene's official symbol. The FKRP gene is also known by other names, listed below.

What is the normal function of the FKRP gene?
The FKRP gene provides instructions for making a protein called fukutin-related protein (FKRP). This protein is present in many of the body's tissues but is particularly abundant in muscles used for movement (skeletal muscles), the brain, and the heart. Within cells, FKRP is found in a specialized structure called the Golgi apparatus, where newly produced proteins are modified.
Although the exact function of FKRP is unclear, researchers predict that it may chemically modify a protein called alpha (α)-dystroglycan. Specifically, FKRP is thought to add chains of sugar molecules to α-dystroglycan through a process known as glycosylation. Glycosylation is critical for the normal function of α-dystroglycan.
The α-dystroglycan protein helps anchor the structural framework inside each cell (cytoskeleton) to the lattice of proteins and other molecules outside the cell (extracellular matrix). In skeletal muscles, glycosylated α-dystroglycan helps stabilize and protect muscle fibers. In the brain, it helps direct the movement (migration) of nerve cells (neurons) during early development.
How are changes in the FKRP gene related to health conditions?
Genetics Home Reference provides information about limb-girdle muscular dystrophy, which is also associated with changes in the FKRP gene.
Where is the FKRP gene located?
Cytogenetic Location: 19q13.32
Molecular Location on chromosome 19: base pairs 46,746,045 to 46,758,574
The FKRP gene is located on the long (q) arm of chromosome 19 at position 13.32.
More precisely, the FKRP gene is located from base pair 46,746,045 to base pair 46,758,574 on chromosome 19.
