Acute monocytic leukemia and multiple abnormalities in a child with duplication of 1q detected by GTG-banding and SKY.
Patients with 1q duplication have demonstrated a wide range of multiple congenital abnormalities. Alterations involving this chromosomal region have being described in hematopoietic malignancies and a series of candidate genes that may be associated with neoplasias have been mapped in this region. We describe a case of partial trisomy 1q "syndrome" and acute monocytic leukemia. Cytogenetic study of the bone marrow cells by GTG-banding and spectral karyotyping (SKY) showed dup(1)(q23q44) in all cells analyzed. The dismorphological features with the dup(1q) suggest a constitutional chromosome alteration and the first, in our knowledge, association of a trisomy 1q "syndrome" with AML.
