Complex small supernumerary marker chromosomes (sSMCs) constitute one of the smallest subsets within the patients with an sSMC. Complex sSMCs consist of chromosomal material derived from more than one chromosome, for example, the derivative der(22)t(11;22)(q23;q11.2) in Emanuel syndrome. Here, a yet unreported case of a complex sSMC formed due to a t(7;9)(p22;q22)mat is presented.
The most common chromosomal abnormality of infant acute lymphoblastic leukemia (ALL) is the t(4;11)(q21;q23) that gives rise to the MLL/AF4 fusion gene. Leukemic blasts expressing MLL/AF4 are arrested at an early progenitor stage with lymphoid or monocytoid characteristics. A novel B-lineage ALL cell line termed B-lineage-3 (BLIN-3) requiring human bone marrow (BM) stromal cell contact and inte...
Here we describe a rare case of an abnormal karyotype with supernumerary derivative chromosome der(22)t(11;22), associated Emanuel syndrome, in boy aged 1 year. Familial cytogenetic analysis revealed the maternal origin anomaly from reciprocal translocation t(11;22) (q23;q11.2). At time examination, child had numerous anomalies development, facial dysmorphia, and small size external genitalia. ...
To the Editor: tion. She received combination chemotherapy and achieved complete remission. However, 1.5 years later, the AML relapsed despite the intermittent intensification, and she died of cerebral bleeding. Karyotype analysis of the blast cells at diagnosis showed 46 XX with the t( I I ; I 7)(q23;q25) translocation in 20 of 20 analyzed cells. The breakpoints of the MLL/ALL-I gene have been...
