The PDGFRA gene, occasionally referred to as the Platelet-Derived Growth Factor Receptor Alpha gene, is a gene that encodes for a receptor protein. The PDGFRA gene is associated with various diseases and conditions, and its proteins play a central role in cell growth and survival.

Changes in the PDGFRA gene can result in the activation of the receptor protein, leading to abnormal cell growth. These changes are often found in certain types of cancer, such as gastrointestinal stromal tumors (GISTs). The PDGFRA gene is also implicated in eosinophilic disorders and other related diseases.

References to the PDGFRA gene can be found in scientific articles and databases such as PubMed and OMIM. These resources provide information on the genetic changes, testing methods, and clinical implications associated with the PDGFRA gene. In addition, the PDGFRA gene is listed in genetic registries and databases, which catalog genetic variants and provide additional information on related disorders.

One common genetic variant of the PDGFRA gene, called the PDGFRA fusion variant, is frequently found in certain types of chronic myeloid leukemia and gastrointestinal stromal tumors. Testing for this variant can be done through genetic tests that target specific changes in the PDGFRA gene. Results from these tests can provide important information for the diagnosis and treatment of patients with PDGFRA-associated diseases.

Genetic changes in the PDGFRA gene have been associated with various health conditions. One group of disorders is called hypereosinophilic disorders, which are characterized by increased levels of eosinophils in the blood.

Eosinophils are a type of white blood cell that play a role in immune response. Changes in the PDGFRA gene can result in a variant of the gene that is called a gain-of-function variant. This variant activates the PDGFRA-associated receptor, leading to abnormal growth and survival of eosinophils.

One of the most common health conditions related to genetic changes in the PDGFRA gene is known as gastrointestinal stromal tumor (GIST). GIST is a type of tumor that can occur in the gastrointestinal tract. PDGFRA fusions genes, in combination with other genetic changes, can lead to the development of GIST.

Other health conditions linked to genetic changes in the PDGFRA gene include chronic eosinophilic leukemia, systemic mastocytosis, and occasionally, other forms of eosinophilic disorders. These conditions are listed in various scientific databases and resources, such as OMIM and PubMed.

If there is a suspicion of a PDGFRA-associated genetic change, diagnostic testing can be performed to confirm the presence of the variant. This testing can include genetic sequencing and analysis of the PDGFRA gene. Additional information on these tests and the related health conditions can be found in published articles and medical references.

It is important for medical professionals to consider possible genetic changes in the PDGFRA gene when evaluating patients with hypereosinophilic disorders, GIST, or other related conditions. Identifying these genetic changes can help guide treatment decisions and improve patient outcomes.

PDGFRA-associated chronic eosinophilic leukemia

PDGFRA-associated chronic eosinophilic leukemia is a type of leukemia that is characterized by the presence of changes in the PDGFRA gene. The PDGFRA gene provides instructions for making a receptor protein that is involved in cell growth and survival. When the PDGFRA gene is altered, it can lead to the growth of abnormal cells, including cancer cells.
