The POMT2 gene, also known as protein O-mannosyl-transferase 2, is a gene that plays a crucial role in the development and functioning of the body. It helps in the process of glycosylation, which is the addition of sugar molecules to proteins, and is related to various genetic disorders.

One of the related conditions is the Walker-Warburg syndrome, also called POMT2-related muscular dystrophy-dystroglycanopathy. This syndrome is characterized by early onset of muscle weakness, brain malformations, and eye abnormalities. Mutations in the POMT2 gene can cause changes in the α-dystroglycan protein, leading to the damaged function of neurons in the brain.

Testing for POMT2-related disorders can be done using genetic testing, and the mutations in this gene are listed in various databases and resources, such as the OMIM (Online Mendelian Inheritance in Man) database and PubMed. These resources provide additional information and scientific articles related to this gene and its associated conditions.

The POMT2 gene is part of a complex network of genes and proteins that are involved in muscular dystrophy and other related disorders. It is usually tested in combination with other genes that are known to be associated with these conditions, such as the limb-girdle muscular dystrophy genes. The catalog of genetic tests and references for these conditions is available in the Genetests.org database.

Understanding the role of the POMT2 gene and its related conditions is important for diagnosing and managing individuals with muscle-eye-brain disorders. By identifying the specific mutations in this gene, healthcare professionals can provide proper genetic counseling and targeted treatment options for affected individuals.

Genetic changes in the POMT2 gene have been associated with various health conditions. Here is a list of some of these conditions:

One of the most important and most popular changes to the health insurance landscape brought about by the passing of the Affordable Care Act was the prohibition against denying patients health insurance, or charging them more, if they had preexisting conditions. Research shows that 27% of Americans in the 18 to 64 age group have what would have been considered a “declinable medical condition” before the Affordable Care Act took effect, and in some regions, the percentage of patients with preexisting conditions rises to nearly four in 10, the Henry J. Kaiser Family Foundation

  • Muscle-eye-brain (MEB) disease: Also called Walker-Warburg syndrome, this rare genetic disorder affects the development of muscles, eyes, and the brain.
  • Limb-girdle muscular dystrophy: Certain variant forms of POMT2 gene mutations can lead to limb-girdle muscular dystrophy, which causes progressive weakness and muscle wasting.
  • α-dystroglycanopathy: Mutations in the POMT2 gene can disrupt the production of α-dystroglycan, a protein necessary for proper muscle and brain development. This can result in various muscular dystrophy-like conditions, including MEB disease.
  • Additional related disorders: Genetic changes in other genes related to POMT2, such as those coding for α-dystroglycan and other proteins involved in glycosylation, can also lead to muscular dystrophy and other related conditions.

Information about these health conditions and the related genetic changes can be found in various scientific resources and databases. Here are some useful resources:

  1. Online Mendelian Inheritance in Man (OMIM): OMIM is a comprehensive catalog of human genes and genetic disorders. It contains detailed information on health conditions associated with POMT2 gene mutations.
  2. The Genetic Testing Registry: This online database provides information on genetic tests related to the POMT2 gene. It includes details on the available tests, their purpose, and the laboratories that perform them.
  3. PubMed: A vast collection of scientific articles, PubMed is a valuable source of research on genetic changes in the POMT2 gene and their implications for health conditions.

Early identification of genetic changes in the POMT2 gene through testing helps in the diagnosis and management of these conditions. It also allows for better understanding of the underlying mechanisms and potential treatment options.

Walker-Warburg syndrome

Walker-Warburg syndrome is a rare genetic disorder that affects the development of the muscles, eyes, and brain. It is also known as muscle-eye-brain syndrome. This syndrome is caused by mutations in the POMT2 gene, which helps in the production of a protein called α-dystroglycan. Changes in this gene can lead to the damaged function of α-dystroglycan, resulting in the characteristic symptoms of Walker-Warburg syndrome.

People with Walker-Warburg syndrome often have weakness in their muscles, including the muscles used for movement and breathing. They may also have problems with their eyes, such as developmental abnormalities or vision loss. The brain is typically affected as well, leading to intellectual disability and developmental delays.

Diagnosis of Walker-Warburg syndrome can be confirmed through genetic testing. The POMT2 gene and other related genes can be analyzed for mutations. Scientific databases like OMIM and PubMed provide additional information on the genetic changes and associated symptoms. The Muscular Dystrophy Association and other resources can offer support and information for affected individuals and their families.

There is currently no cure for Walker-Warburg syndrome, but treatments and interventions can help manage its symptoms and improve quality of life. These may include physical therapy, speech therapy, and interventions for vision impairments. Ongoing research is focused on understanding the underlying causes of the syndrome and developing potential therapies.
