The PHKA2 gene is a genetic mutation that is responsible for a rare metabolic disease known as Glycogen Storage Disease Type IXa. Although this gene is not well known, scientific research and registries have been established to gather information and provide resources for those affected by this condition.
Phosphorylase kinase, alpha 2 (PHKA2) is a gene listed in the PubMed database. It is known to be involved in the storage and breakdown of glycogen in various tissues. This gene is one of the subunits of the phosphorylase kinase enzyme, which plays a crucial role in glycogen metabolism.
The PHKA2 gene has been linked to a specific variant of Glycogen Storage Disease Type IXa. This variant is characterized by changes in the PHKA2 gene, which result in a dysfunctional enzyme and impaired glycogen storage. This can lead to various health conditions and symptoms associated with the improper storage of glycogen.
Further information about the PHKA2 gene and related genes can be found in databases such as OMIM (Online Mendelian Inheritance in Man) and other genetic resources. These resources provide additional research articles, testing protocols, and information about related diseases and conditions.
Overall, the PHKA2 gene plays a significant role in glycogen storage and metabolism. Understanding its function and the genetic changes that can occur in this gene is crucial for diagnosing and managing Glycogen Storage Disease Type IXa and related conditions.
Health Conditions Related to Genetic Changes
Genetic changes in the PHKA2 gene can result in various health conditions. These changes can be classified into different types of glycogen storage diseases, specifically those that affect the phosphorylase enzyme.
Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.
Although there are other genes that are associated with glycogen storage diseases, this article will focus on the PHKA2 gene.
The PHKA2 gene provides instructions for making a subunit of the phosphorylase enzyme. Mutations in this gene can lead to a deficiency or a variant form of this enzyme, causing glycogen storage diseases.

Glycogen storage disease type IX
Glycogen storage disease type IX, also known as GSD IX, is a genetic condition caused by changes in the PHKA2 gene. This gene provides instructions for producing one of the subunits of the enzyme phosphorylase, which is responsible for breaking down glycogen into glucose in various tissues.
Glycogen storage diseases are a group of conditions in which the body cannot properly break down or store glycogen, resulting in abnormal glycogen accumulation in tissues. GSD IX is specifically caused by mutations in the PHKA2 gene.
OMIM, a catalog of human genes and genetic conditions, provides more information on GSD IX. There are scientific articles related to this disease listed in PubMed, a database for scientific and health-related research. Additional resources can be found in other databases and registries.
Tests for GSD IX can be done to confirm the diagnosis. These tests usually involve examining the PHKA2 gene for changes or mutations. Genetic testing can help identify the specific variant of the gene that is causing the disease.
GSD IX can affect various tissues in the body, including the liver and muscle. The symptoms and severity of the disease can vary depending on the specific genetic changes and the affected tissues. Some individuals may experience mild symptoms, while others may have more severe complications.
Although there is currently no cure for GSD IX, management options are available to help control symptoms and prevent complications. Treatment may involve dietary adjustments, enzyme replacement therapy, and regular monitoring of glycogen storage levels.
