Distal myopathy 2, also known as Welander distal myopathy, is a rare genetic condition characterized by muscle weakness and wasting, especially in the distal muscles of the hands and feet. It is inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to each of their children.

The frequency of distal myopathy 2 varies among different populations and geographic regions. It is more commonly found in people of Swedish and Finnish descent, but cases have been reported in other populations as well.

The condition is caused by mutations in the gene known as TIA1, which provides instructions for making a protein that plays a role in regulating the formation of cellular inclusions called stress granules. These stress granules are involved in the response to cellular stress and are essential for the normal function of cells.

Patients with distal myopathy 2 typically present with muscle weakness and atrophy that begins in the distal extremities, such as the hands and feet, and progresses slowly over time. Other symptoms may include difficulty swallowing (dysphagia), a hoarse voice, and weakness in the muscles responsible for voice production (larynx). The condition does not affect the sensation or coordination of the muscles.

Diagnosis of distal myopathy 2 can be confirmed through genetic testing that identifies mutations in the TIA1 gene. Additional tests, such as electromyography and muscle biopsy, may be performed to rule out other causes of muscle weakness and wasting.

Currently, there is no specific treatment for distal myopathy 2. Management focuses on supportive care, such as physical therapy to maintain muscle strength and mobility, assistive devices to aid in daily activities, and swallowing techniques to improve dysphagia. Regular monitoring of respiratory function is also important, as weakness in the respiratory muscles can occur in some cases.

Americans see their primary care doctors less often than they did a decade ago. Adults under 65 made nearly 25% fewer visits to primary care providers in 2016 than they did in 2018, according to National Public Radio. In the same time period, the number of adults who went at least a year without visiting a primary care provider increased from 38% to 46%.

For more information about distal myopathy 2 and other rare genetic diseases, there are several resources available, including advocacy organizations, scientific articles, and online databases. The Online Mendelian Inheritance in Man (OMIM) catalog and PubMed provide a wealth of scientific articles and references, while advocacy organizations like the Muscular Dystrophy Association and the Myopathy Information Center offer support and information for patients and families.

Distal myopathy 2 is a rare condition with a complex genetic basis. Understanding the underlying causes and mechanisms of the disease can provide valuable insights into the normal function of muscle proteins and cellular processes. Through ongoing research and collaboration, scientists and clinicians can continue to learn more about this condition and develop new strategies for diagnosis, management, and potential treatments.

Causes

Distal myopathy 2, also known as distal myopathy with vocal cord and pharyngeal weakness, is a rare genetic condition. It is caused by mutations in the MATR3 gene, which encodes for the matrin-3 protein. Matrin-3 is found in the nucleus and plays a role in maintaining the structure and function of the nuclear matrix.

This condition has an autosomal dominant inheritance pattern, meaning that a person with one copy of the mutated gene will develop the condition. In some cases, the condition may occur sporadically, without a family history of the condition. The frequency of this condition is rare, and more research is needed to fully understand its prevalence.

The exact mechanisms by which mutations in the MATR3 gene cause distal myopathy 2 are still being studied. However, it is believed that the mutated gene affects the function of matrin-3, leading to the muscle weakness and other symptoms associated with the condition.

Other genetic diseases that are associated with mutations in nuclear matrix proteins or genes include Emery-Dreifuss muscular dystrophy, limb-girdle muscular dystrophy, and centronuclear myopathy. While these conditions may share some similarities with distal myopathy 2, they are separate diseases with distinct genetic causes.

More research is needed to fully understand the mechanisms by which these mutations cause the condition. Further investigation into the genetic causes of distal myopathy 2 may provide insights into potential treatments and management strategies for patients.
