What does the DMPK gene do?
The DMPK gene provides instructions for making a protein called myotonic dystrophy protein kinase. This protein appears to play an important role in muscle, heart, and brain cells.
What proteins are affected in myotonic dystrophy?
The protein produced from the CNBP gene is found primarily in the heart and in skeletal muscles, where it helps regulate the function of other genes. Similar changes in the structure of the DMPK and CNBP genes cause myotonic dystrophy type 1 and type 2.
What are the symptoms of myotonic muscular dystrophy?
Signs and symptoms of myotonic dystrophy often begin in a person’s 20s or 30s but can begin at any age. Symptoms often include progressive muscle weakness, stiffness, tightness, and wasting.
What is congenital myotonic muscular dystrophy?
Congenital myotonic dystrophy (CMD) is a multisystem disease affecting many organs in the body. It is caused by a mutation in the DMPK gene. Infants appear weak, and sometimes require help with breathing and feeding. It is usually diagnosed by genetic testing for the targeted gene.
Where is the DMPK gene?
Myotonin-protein kinase (MT-PK) also known as myotonic dystrophy protein kinase (MDPK) or dystrophia myotonica protein kinase (DMPK) is an enzyme that in humans is encoded by the DMPK gene….Myotonin-protein kinase.

What is the genetic code for dystrophin?
DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle.
Is CK elevated in myotonic dystrophy?
Individuals with DM may have mildly or moderately elevated levels of a muscle enzyme called creatine kinase or CK in their blood serum. Some individuals have low levels of immunoglobulin G.
What nucleotides are repeated in myotonic dystrophy?
DNA expansion in DMPK gene causes DM1 The defect was identified in 1992 as the cause of DM1. The DNA building blocks cytosine, thymine, and guanine (abbreviated as CTG) are repeated many more times than average in this disorder.
What happens if myotonic dystrophy is left untreated?
Heart problems. Muscular dystrophy can reduce the efficiency of the heart muscle. Swallowing problems. If the muscles involved with swallowing are affected, nutritional problems and aspiration pneumonia can develop.
Is myotonic dystrophy curable?
There is currently no cure or specific treatment for myotonic dystrophy. Ankle supports and leg braces can help when muscle weakness gets worse. There are also medications that can lessen the myotonia. Other symptoms of myotonic dystrophy such as the heart problems, and eye problems (cataracts) can also be treated.
The DMPK gene provides instructions for making a protein called myotonic dystrophy protein kinase. This protein appears to play an important role in muscle, heart, and brain cells. The protein may be involved in communication within cells.
Does a protein kinase play a role in myotonic dystrophy?
The involvement of a protein kinase in myotonic dystrophy is consistent with the pivotal role of such enzymes in a wide range of biochemical and cellular pathways, and was indeed predicted by Roses and Appel (1974).
What does DMPK stand for?
Myotonic dystrophy protein kinase (DMPK) and its role in the pathogenesis of myotonic dystrophy 1 Myotonic dystrophy 1 (DM1) is an autosomal, dominant inherited, neuromuscular disorder.
What does MDPK stand for?
Myotonin-protein kinase. Myotonin-protein kinase (MT-PK) also known as myotonic dystrophy protein kinase (MDPK) or dystrophia myotonica protein kinase (DMK) is an enzyme that in humans is encoded by the DMPK gene. The dmpk gene product is a Ser/Thr protein kinase homologous to the MRCK p21-activated kinases and the Rho family of kinases.
