Is Acute myelogenous leukemia (AML) hereditary?

Acute myelogenous leukemia (AML) is generally considered a genetic disease because it is caused by mutations in the DNA of blood-forming cells, but it is rarely hereditary. In the vast majority of cases, Acute myelogenous leukemia (AML) arises from somatic mutations—changes that occur during a person's lifetime—rather than being passed down from parents.

Is Acute myelogenous leukemia (AML) hereditary?

While Acute myelogenous leukemia (AML) is a cancer of the genetic material, it is not typically inherited. Most patients develop the disease due to sporadic, de novo (new) mutations in hematopoietic stem cells. Although rare, there are documented cases of familial Acute myelogenous leukemia (AML), where specific germline mutations (inherited genetic changes) predispose individuals to the disease. These familial forms often involve genes such as RUNX1, CEBPA, or GATA2, but they account for a very small percentage of total cases.

What is the role of genetic testing in AML?

Genetic testing for Acute myelogenous leukemia (AML) is standard practice, but it usually focuses on somatic mutations within the tumor cells to guide treatment, rather than identifying inherited risks. If a physician suspects a hereditary predisposition, they may recommend germline testing. Factors that might trigger a referral for genetic counseling include:

• A strong family history of hematologic malignancies.


• Diagnosis of Acute myelogenous leukemia (AML) at a very young age.


• Presence of physical anomalies or developmental delays alongside the leukemia.


• Personal history of multiple different cancers.

How does germline testing impact family planning?

If a germline mutation is identified, the risk to children depends on the specific gene involved, with many familial forms following an autosomal dominant pattern. Genetic counselors provide essential support by helping families understand these risks. When a hereditary predisposition is confirmed, options for those planning pregnancies may include:

1. Preimplantation Genetic Testing (PGT) alongside IVF.


2. Prenatal diagnostic testing (CVS or amniocentesis).


3. Cascade testing for at-risk family members to provide early screening and surveillance.

Next steps

• Consult a hematologist-oncologist to discuss if your specific case requires germline genetic testing.
