AML with RUNX1::RUNX1T1 Cooperating two Mutations Relapsed Quickly after Achieving CR
Clinical Laboratory
|March 12, 2024
Summary
Acute myeloid leukemia with t(8;21) typically has a good prognosis. However, this case shows relapse despite complete remission, highlighting complex genetic factors in AML.
Area of Science:
- Hematology
- Oncology
- Molecular Biology
Background:
- Acute myeloid leukemia (AML) with the t(8;21) translocation, characterized by the RUNX1::RUNX1T1 fusion gene, generally presents a favorable prognosis.
- Patients with this subtype often achieve high complete remission rates and long disease-free survival.
Observation:
- This report details a patient diagnosed with AML harboring the t(8;21) translocation.
- The patient's leukemia exhibited myelomonocytic differentiation and presented with additional genetic abnormalities, including KRAS and ASXL1 cooperating mutations and a del(17) karyotype abnormality.
Findings:
- Despite achieving a morphologic complete remission (CR), the patient experienced disease relapse.
- The presence of cooperating mutations and additional karyotype abnormalities may influence treatment response and prognosis in t(8;21) AML.
Implications:
- This case underscores the importance of comprehensive genetic profiling in AML, even in subtypes with a generally favorable outlook.
- Further research is needed to understand how cooperating mutations impact therapeutic strategies and outcomes in t(8;21) AML patients.
- Identifying such complex genetic landscapes is crucial for refining prognostic models and developing targeted therapies.

01:20Mismatch Repair
4.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

03:18Non-LTR Retrotransposons
11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

02:23Abnormal Proliferation
4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

02:53Conservative Site-specific Recombination and Phase Variation
6.0K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

01:20The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:56Treatment Resistant Cancers
3.3K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
