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

What is the normal function of the PLEC gene?
The PLEC gene provides instructions for making a protein called plectin. This protein is produced in many different tissues in the body, including skin and muscle. Within cells, plectin interacts with several molecules that make up the cell's structural framework (the cytoskeleton). For example, plectin interacts with intermediate filaments, which form networks that provide support and strength to cells. Plectin attaches (cross-links) intermediate filaments to one another and to the cell membrane.
The exact function of plectin in different tissues is unclear. In skin cells, this protein is an essential part of structures called hemidesmosomes, which attach the network of intermediate filaments to the cell membrane. It is also a component of desmosomes, which form junctions between neighboring cells. As part of these structures, plectin plays a critical role in anchoring the outer layer of the skin (the epidermis) to underlying layers.
How are changes in the PLEC gene related to health conditions?
Genetics Home Reference provides information about congenital myasthenic syndrome, which is also associated with changes in the PLEC gene.
Where is the PLEC gene located?
Cytogenetic Location: 8q24
Molecular Location on chromosome 8: base pairs 143,915,147 to 143,976,792
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The PLEC gene is located on the long (q) arm of chromosome 8 at position 24.
More precisely, the PLEC gene is located from base pair 143,915,147 to base pair 143,976,792 on chromosome 8.
