Failure of NIPT to detect constitutional chromoanasynthesis involving chromosome 21 in a case of fetal hydrops—A case report [PDF]
We report a case of a de novo ring 21 complex chromosomal rearrangement in a fetus presenting with hydrops. Noninvasive prenatal testing (NIPT) failed to detect the imbalance.

Mitotic microhomology-mediated break-induced replication promotes chromoanasynthesis [PDF]
Chromoanasynthesis is a form of complex chromosomal rearrangement (CCR) commonly detected in cancers and congenital disorders, but the mechanism underlying its generation remain elusive. Here we develop a single-molecule long-read DNA sequencing approach

Chromoanasynthesis is a common mechanism that leads to ERBB2 amplifications in a cohort of early stage HER2+ breast cancer samples [PDF]
Background HER2 positive (HER2+) breast cancers involve chromosomal structural alterations that act as oncogenic driver events. Methods We interrogated the genomic structure of 18 clinically-defined HER2+ breast tumors through integrated analysis of ...

Chromoanasynthesis as a cause of Jacobsen syndrome [PDF]
AbstractJacobsen syndrome (MIM #147791) is a rare multisystem genomic disorder involving craniofacial abnormalities, intellectual disability, other neurodevelopmental defects, and terminal truncation of chromosome 11q, typically deleting ~170 to >340 genes.

Chromoanagenesis in Osteosarcoma [PDF]
Chromoanagenesis is a catastrophic genomic phenomenon involving sudden, extensive rearrangements within one or a few cell cycles. In osteosarcoma, the most prevalent malignant bone tumor in children and adolescents, these events dramatically alter the ...

Marker chromosome genomic structure and temporal origin implicate a chromoanasynthesis event in a family with pleiotropic psychiatric phenotypes [PDF]
Small supernumerary marker chromosomes (sSMC) are chromosomal fragments difficult to characterize genomically. Here, we detail a proband with schizoaffective disorder and a mother with bipolar disorder with psychotic features who present with a marker chromosome that segregates with disease.

Centromeric instability and chromoanasynthesis observed in nine supernumerary marker chromosomes resolved with long-read genome sequencing [PDF]
Small supernumerary marker chromosomes (sSMCs) remain a diagnostic challenge despite sequencing advances. As the field shifts toward cytogenomics, there is a need to establish methodologies to resolve these complex genetic variants at base pair resolution, as well as to identify their chromosomal origin and formation mechanism. Here, we apply long-read

Case Report: The molecular profile of granular cell astrocytoma predicts aggressive clinical behavior, independent of morphology [PDF]
BackgroundGranular cell astrocytoma (GCA) is a rare, morphologically distinct variant of IDH-wildtype glioblastoma that can appear deceptively low-grade yet behave aggressively.
