What is the official name of the MYOT gene?
The official name of this gene is “myotilin.”
MYOT is the gene's official symbol. The MYOT 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 MYOT gene?
The MYOT gene provides instructions for making a protein called myotilin. Myotilin is found in heart (cardiac) muscle and muscles used for movement (skeletal muscle). Within muscle fibers, myotilin proteins are found in structures called sarcomeres, which are necessary for muscles to tense (contract). Myotilin attaches (binds) to other proteins to help form sarcomeres. Myotilin is also involved in linking neighboring sarcomeres to each another to form myofibrils, the basic unit of muscle fibers. The connection of sarcomeres to each other and the formation of myofibrils are essential for maintaining muscle fiber strength during repeated cycles of contraction and relaxation.
Does the MYOT gene share characteristics with other genes?
The MYOT gene belongs to a family of genes called immunoglobulin superfamily, I-set domain containing (immunoglobulin superfamily, I-set domain containing).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the MYOT gene related to health conditions?
Genetics Home Reference provides information about limb-girdle muscular dystrophy, which is also associated with changes in the MYOT gene.
Where is the MYOT gene located?
Cytogenetic Location: 5q31
Molecular Location on chromosome 5: base pairs 137,203,535 to 137,223,539
The MYOT gene is located on the long (q) arm of chromosome 5 at position 31.
More precisely, the MYOT gene is located from base pair 137,203,535 to base pair 137,223,539 on chromosome 5.
