WebConclusion: This study demonstrated that coamplification of genes located on the 11q13.3 amplicon is frequently detected in luminal B subtype breast cancer and is closely associated with worse survival in patients with breast cancer. Moreover, coamplification of the CCND1-FGF locus might decrease antitumor immune activity in breast cancer ...

WebLe mécanisme évoqué est celui de chromoanasynthesis, responsable de la formation de plusieurs types de remaniements (délétion, duplication, triplication, inversion, translocation,…). L’utilisation des nouvelles techniques de séquençage haut-débit pourront permettre d’aller plus loin dans la compréhension du mécanisme. WebChromoanasynthesis has been described as a novel cause of massive constitutional chromosomal rearrangements. Based on DNA replication machinery defects, chromoanasynthesis is characterized by the presence of chromosomal duplications and triplications locally clustered on one single chromosome, or a few chromosomes, …
