This study details two new cases of a specific chromosomal abnormality, the t(1;7) translocation, observed in patients with hematologic disorders. This finding adds to the limited understanding of this rare genetic alteration in blood diseases.

Area of Science:

Cytogenetics
Hematology
Human Genetics

Background:

The t(1;7) translocation, specifically t(1;7)(p11;p11), is a rare chromosomal abnormality.
This translocation results in trisomy for the 1q region and monosomy for the 7q region in abnormal cells.
Previously reported in eight patients with hematologic disorders, with four additional cases found in the literature.

Observation:

This report presents two new patients exhibiting the t(1;7) translocation.
The karyotype analysis confirmed trisomy 1q and monosomy 7q in the abnormal cells of these patients.

Findings:

The two new cases contribute to the small but growing body of evidence on t(1;7)(p11;p11).
Consistent karyotypic findings (trisomy 1q, monosomy 7q) are observed across reported cases.

Implications:

Further research is needed to elucidate the specific role of t(1;7)(p11;p11) in the pathogenesis of hematologic disorders.
Understanding this translocation may aid in diagnosis and prognosis for affected individuals.
Adds to the cytogenetic knowledge base for hematologic malignancies.
