Abstract
OBJECTIVE We present prenatal diagnosis and molecular cytogenetic characterization of an inverted duplication of proximal chromosome 15 [inv dup(15)] presenting as a small supernumerary marker chromosome (sSMC) at amniocentesis associated with concomitant microduplication of 8q22.1. MATERIALS AND METHODS A 39-year-old woman underwent amniocentesis at 16 weeks of gestation because of advanced maternal age, and the result was 47, XY, +mar dn. The woman requested for repeat amniocentesis at 20 weeks of gestation. Array comparative genomic hybridization (aCGH), fluorescence in situ hybridization (FISH), quantitative fluorescent polymerase chain reaction (QF-PCR) and DNA methylation analysis were applied to determine the nature of the sSMC. RESULTS aCGH on the uncultured amniocytes revealed the result of arr 8q22.1 (93,918,763-96,618,539) × 3.0, arr 15q11.2q13.2 (22,765,628-30,658,876) × 4.0, arr 15q13.2q13.3 (30,653,877-32,509,926) × 3.0 [GRCh37 (hg19)]. Interphase FISH analysis using RP11-34H12 [15q13.2; Texas Red, 30,709,033-30,893,021 (hg19)] on 100 uncultured amniocytes showed that 38 cells had three signals, 45 cells had four signals and 27 cells had two signals. The parental bloods had normal aCGH results. The karyotype of cultured amniocytes was 47, XY, +inv dup(15) (pter→q13::q13→pter) which was confirmed by metaphase FISH analysis. No informative markers could be found in QF-PCR analysis. DNA methylation analysis on cord blood confirmed a maternal origin of the 15q11-q13 gene dosage increase with a result of 15q11.2 SNRPN DNA hypermethylation. Postnatal cytogenetic analysis on cord blood, umbilical cord and placenta showed the results consistent with the prenatal diagnosis. CONCLUSION Molecular cytogenetic techniques are useful for rapid diagnosis of an inv dup(15) chromosome presenting as an sSMC at amniocentesis.

Abstract
The molecular landscape in non-muscle-invasive bladder cancer (NMIBC) is characterized by large biological heterogeneity with variable clinical outcomes. Here, we perform an integrative multi-omics analysis of patients diagnosed with NMIBC (n = 834). Transcriptomic analysis identifies four classes (1, 2a, 2b and 3) reflecting tumor biology and disease aggressiveness. Both transcriptome-based subtyping and the level of chromosomal instability provide independent prognostic value beyond established prognostic clinicopathological parameters. High chromosomal instability, p53-pathway disruption and APOBEC-related mutations are significantly associated with transcriptomic class 2a and poor outcome. RNA-derived immune cell infiltration is associated with chromosomally unstable tumors and enriched in class 2b. Spatial proteomics analysis confirms the higher infiltration of class 2b tumors and demonstrates an association between higher immune cell infiltration and lower recurrence rates. Finally, the independent prognostic value of the transcriptomic classes is documented in 1228 validation samples using a single sample classification tool. The classifier provides a framework for biomarker discovery and for optimizing treatment and surveillance in next-generation clinical trials.
