Myeloid neoplasms with germ line RUNX1 mutation

Area of Science:

• Hematology
• Genetics
• Oncology

Background:

• Familial platelet disorder with propensity to myeloid malignancies (FPD/AML) is an inherited condition.
• It involves platelet abnormalities and a high risk of developing blood cancers.
• Germline mutations in the RUNX1 gene are the known cause.

Purpose of the Study:

• To provide an updated review of FPD/AML.
• To discuss recent clinical and experimental findings related to the disorder.
• To highlight the significance of germline RUNX1 mutations in hematological malignancies.

Main Methods:

• This is a review article, synthesizing existing literature.
• It incorporates recent clinical observations and experimental data.
• The review references the revised WHO 2016 classification.

Main Results:

• FPD/AML is an autosomal dominant disorder linked to heterozygous germline RUNX1 mutations.
• Approximately 50% of individuals with these mutations develop hematological malignancies.
• The average age of diagnosis is over 30 years, indicating a long latency period.
• Acquired genetic events cooperate with inherited RUNX1 mutations in disease progression.

Conclusions:

• FPD/AML is a significant inherited risk factor for myeloid malignancies.
• RUNX1 mutations play a critical role in both familial and sporadic hematological cancers.
• Increased recognition has led to its inclusion in updated classifications of hematological disorders.
