Cytogenetically normal acute myeloid leukemia (CN-AML) is a type of leukemia that is characterized by normal genetic changes in the bone marrow cells of patients. This condition leads to the abnormal growth of white blood cells, specifically myeloid cells, which are responsible for fighting infections and promoting blood clotting.
In CN-AML, the karyotype, or the visual representation of an individual’s chromosomes, shows no abnormalities. However, recent studies have associated specific genetic changes, such as mutations in the NPM1 or FLT3 genes, with this condition. These genetic changes are likely to play a role in the development and progression of CN-AML.
Patients with CN-AML typically present with symptoms such as fatigue, frequent infections, and easy bruising or bleeding. The condition can be diagnosed through bone marrow biopsy and genetic testing to identify the specific genetic changes associated with CN-AML.
Additional resources and support for patients with CN-AML can be found through organizations such as Curr Hematol Rep and the National Library of Medicine’s Online Mendelian Inheritance in Man (OMIM) catalog. These resources provide information on the clinical trials, research articles, and advocacy groups related to CN-AML.
Frequency
The frequency of cytogenetically normal acute myeloid leukemia (CN-AML) is about 45-50% of all cases of AML. CN-AML is a condition characterized by the absence of detectable chromosomal abnormalities when tested with traditional karyotype testing. However, it is important to note that additional molecular testing may reveal genetic changes or mutations that are associated with this condition.
For patients with CN-AML, the most likely genetic mutation is in the nucleophosmin 1 (NPM1) gene. NPM1 mutations are found in approximately 50-60% of CN-AML cases.

More information on the frequency and genetic causes of CN-AML can be found in scientific articles and research studies. Resources such as PubMed, OMIM, and clinicaltrialsgov provide a catalog of articles and studies that can be helpful in learning more about this condition.

Causes
Cytogenetically normal acute myeloid leukemia (CN-AML) is a form of acute myeloid leukemia (AML) that does not show any visible chromosomal abnormalities under scientific examination. The cause of CN-AML is not fully understood, but several factors are likely to play a role in its development.
Genetic changes in certain genes, such as NPM1, have been associated with CN-AML. These changes can lead to abnormal growth and development of white blood cells and platelets in the bone marrow.
In some cases, CN-AML may be inherited, suggesting a genetic component to the condition. However, the inheritance pattern of CN-AML is not well-defined, and further research is needed to understand the genetic factors involved.
Other causes of CN-AML may include environmental factors, such as exposure to certain chemicals or radiation. However, the exact role of these factors is still unclear and requires further investigation.
Currently, there are no specific advocacy groups or resources dedicated solely to CN-AML. However, patients and their families can find support and information from general leukemia advocacy organizations, such as the National Organization for Rare Disorders (NORD) or the Leukemia & Lymphoma Society.

Learn more about the genes associated with Cytogenetically normal acute myeloid leukemia
Cytogenetically normal acute myeloid leukemia (CN-AML) is a condition characterized by the presence of certain genetic changes in the cells of the bone marrow. In CN-AML, there are no visible changes in the chromosomes of the cells when viewed under a microscope, hence the term “cytogenetically normal”. This condition accounts for about 50%-60% of all AML cases.
While the causes of CN-AML are not entirely understood, research has shown that certain genetic mutations play a role in the development of this condition. One of the most common gene mutations associated with CN-AML is the NPM1 gene mutation. The NPM1 gene provides instructions for making a protein that is involved in regulating cell growth. Mutations in this gene can lead to the overproduction of white blood cells, which can contribute to the development of CN-AML.
Other genes that have been associated with CN-AML include FLT3, DNMT3A, IDH1, and IDH2. These genes are also involved in regulating cell growth and play important roles in the development and function of blood cells.
Research studies have shown that CN-AML patients who have certain gene mutations, such as NPM1 or FLT3, may have different clinical outcomes compared to patients without these mutations. Understanding the genetic profile of CN-AML patients can provide valuable information for prognosis and treatment decisions.
For patients with CN-AML, genetic testing can help identify specific gene mutations that may be present. This information can be useful in guiding treatment decisions and developing targeted therapies. Genetic testing can also provide valuable information about the likelihood of disease recurrence and response to certain treatments.
If you or a loved one has been diagnosed with CN-AML, it is important to learn more about the genes associated with this condition. The following resources can provide more information and support:
- Scientific articles and studies: These resources can provide in-depth information about the genetic changes associated with CN-AML. PubMed and other scientific databases are useful for accessing the latest research findings.

This knowledge can help guide treatment decisions and support ongoing research efforts to improve outcomes for individuals with CN-AML.
Inheritance
The development of cytogenetically normal acute myeloid leukemia (CN-AML) is likely influenced by both genetic and environmental factors. The genetic changes associated with CN-AML can occur spontaneously and are not inherited or passed down from parents. However, certain genetic mutations can increase the risk of developing CN-AML.
Several genes have been found to be associated with the development of CN-AML. The most commonly mutated gene in CN-AML is NPM1, which is involved in cell growth and plays a role in regulating gene expression. Additional genetic changes can also occur, leading to alterations in the normal function of genes involved in the growth and development of blood cells.
While the exact inheritance pattern of CN-AML is not well understood, research suggests that it is a complex condition influenced by multiple genes and environmental factors. Genetic studies have provided valuable information about the genes and pathways involved in CN-AML, but more research is needed to fully understand the inheritance and causes of this condition.
There are resources available for patients and families affected by CN-AML, including advocacy groups, clinical trials, and support organizations. The OMIM database and PubMed are valuable sources of scientific information and references about CN-AML and its genetic changes. The Fulton Genetics and Hematol catalog provides additional resources for genetic testing and studies related to CN-AML and other myeloid diseases.
It is important for individuals diagnosed with CN-AML to work with their healthcare providers to learn more about their specific condition and treatment options. Genetic testing may be recommended to determine the presence of specific genetic mutations that can help guide treatment decisions and provide prognostic information.
