The enrichment of breakpoints in late-replicating chromatin

WebChromoanasynthesis is a subtype of chromoanagenesis, a term used to describe the single-step processes by which complex chromosomal rearrangements lead to localized structural genomic reorganization of one or a few chromosomes. During chromoanasynthesis, complex chromosomal rearrangements are mediated by replication-based mechanisms … 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 ... WebChromoanasynthesis was first characterized by CMA, fluorescence in situ hybridization (FISH), and karyotyping, which brought to light complex combinations of clustered deletions, duplications, triplications, inversions, and translocations in subjects with diverse congenital anomalies.
