Prevalence of 7q deletion in patients with Acute myeloid leukemia
Introduction: Deletion of critical regions on long arm of chromosome 7 is important in pathogenesis of acute myeloid leukemia (AML). These regions include 7q22 and 7q31 which carry certain tumor suppressor genes which if deleted can result in uncontrolled division of myeloid cells. Aims: To estimate...

| description | Introduction: Deletion of critical regions on long arm of
chromosome 7 is important in pathogenesis of acute myeloid
leukemia (AML). These regions include 7q22 and 7q31 which
carry certain tumor suppressor genes which if deleted can
result in uncontrolled division of myeloid cells.
Aims: To estimate prevalence of 7q deletion in patients with
acute myeloid leukemia (AML).
Materials and methods: Retrospective study was done on 25
bone marrow samples diagnosed with Acute myeloid leukemia
referred to Division of Human Genetics St.John’s Medical
college, Bangalore. Samples were subjected to standard
protocol for karyotyping and FISH. Percentage of patients who
were positive for 7q deletion was calculated.
Results: Out of 25 samples, 5 samples were positive for 7 q
deletion accounting to 20% of total patients diagnosed with
AML.
Conclusion: Presence of 7q deletion can be a poor prognostic
marker since tumour suppressor genes are present in these
regions. Hence cytogenetic markers are very important in
deciding treatment and prognosis in these patients. |
