How common is myotonic dystrophy type 2?
There are few epidemiologic studies of DM2. The exact prevalence of DM2 is not known. DM1 affects at least 1 in 8,000 people worldwide but the prevalence of the two types of myotonic dystrophy varies among different geographic and ethnic populations.
Does myotonic dystrophy get worse with each generation?
Mutation of the DMPK gene causes myotonic dystrophy type 1 (DM1). Mutation of CNBP gene causes type 2 (DM2). DM is typically inherited from a person’s parents, following an autosomal dominant inheritance pattern, and it generally worsens with each generation.
Is myotonic dystrophy a terminal illness?
In the most severe cases, respiratory and cardiac complications can be life-threatening even at an early age. In general, the younger an individual is when symptoms first appear, the more severe symptoms are likely to be. However, prognosis is as variable as the symptoms of this disease.
Is myotonic dystrophy type 2 a disability?
If you have myotonic dystrophy (DM) and are unable to work due to a DM-related disability and/or other conditions, you may be entitled to Social Security Disability Insurance (SSDI) benefits or Supplemental Security Income (SSI) benefits available through the Social Security Administration (SSA).
What is the prognosis for people with myotonic dystrophy?
MedlinePlus Genetics contains information on Myotonic dystrophy.
How do people get myotonic dystrophy?
“Myotonic dystrophy is typically inherited from a person’s parents, following an autosomal dominant inheritance pattern. There are two main types: type 1 (DM1), due to mutations in the DMPK gene, and type 2 (DM2), due to mutations in the CNBP gene. The disorder generally worsens in each generation. A type of DM1 may be apparent at birth.
Is myotonic dystrophy a fatal disease?
Myotonic dystrophy type 1 involves cardiac conduction disorders. Cardiac conduction disease can cause fatal arrhythmias or sudden death in patients with myotonic dystrophy type 1.
What are the most common myotonic dystrophy symptoms?
– Intellectual disabilities can be seen in all types but are not universal for all types of DM. – Cerebrovascular accidents can occur secondary to DM associated atrial fibrillation. – Anxiety and depression due to the loss of functional status – Hypersomnia and sleep apnea are common due to sleep cycle dysfunctions. – Ventriculomegaly is seen in congenital DM.
