Proximal 10q duplication is a well-defined but rare genetic syndrome. Duplication of proximal segments of the long arm of chromosome 10 results in a pattern of malformations, which are distinct from those of the more common distal 10q trisomy syndrome. The present study describes the case of a boy with ...

Pure/direct duplications on the long arm of chromosome 4 represent an infrequent chromosomal finding. Description of clinical findings in 30 patients has resulted in defining the 4q-associated phenotype. However, such duplications have not been molecularly or genomically characterized yet, limiting genotype-phenotype correlation. We report on the first two patients with ...

Deletion of the Ikaros (IKZF1) gene is an oncogenic lesion frequently associated with BCR-ABL1-positive acute lymphoblastic leukemias. It is also found in a fraction of BCR-ABL1-negative B-cell precursor acute lymphoblastic leukemias, and early studies showed it was associated with a higher risk of relapse. Therefore, screening tools are needed for ...

One of the two X chromosomes in cells of female mammals is transcriptionally silenced in a process known as X chromosome inactivation (XCI). Initiation of XCI is regulated by the ubiquitin ligase Rnf12/RLIM, but the mechanisms by which Rnf12/RLIM mediates this process has been a mystery. A recent study by ...
