Retrospective chromosome microarray analysis of 83 genes within the fibroblast growth factor signaling pathway in 52 patients with heterogeneous differences in sex development (DSD) revealed small copy-number variations (CNVs) in ~31% (=26) of investigated genes. Roughly half of these genes (39/83) are ⩽50 kb. This study highlights the potential involvement of small CNVs in disrupting normal gene function and dysregulating genes of the FGF pathway associated with DSD.

Introduction: MET amplification (METamp) can be a de novo or acquired resistance driver; however, the definition of METamp that best captures patients who may respond to targeted therapy remains debated. We explored the genomic landscape of METamp NSCLC including degree of amplification, co-drivers, amplicon size, and outcomes to MET inhibitors.
Methods: Hybrid-capture NGS-based genomic profiling from 88,547 tissue and 12,428 liquid NSCLC samples were queried for METamp (copy number (CN) ≥ ploidy + 4, or amplification ratio (AmpRatio; [CN/sample ploidy] ≥ 3).

Carcinogenesis often involves significant alterations in the cancer genome, marked by large structural variants (SVs) and copy number variations (CNVs) that are difficult to capture with short-read sequencing. Traditionally, cytogenetic techniques are applied to detect such aberrations, but they are limited in resolution and do not cover features smaller than several hundred kilobases. Optical genome mapping (OGM) and nanopore sequencing [Oxford Nanopore Technologies (ONT)] bridge this resolution gap and offer enhanced performance for cytogenetic applications.

Aim: The study was designed to evaluate molecular alterations, relevant to the prognosis and personalized therapy of salivary gland cancers (SGCs).
Materials And Methods: DNA was extracted from archival tissue of 40 patients with various SGCs subtypes. A targeted next-generation sequencing (NGS) panel was used for the identification of small-scale mutations, focal and chromosomal arm-level copy number changes.

The sex chromosomes contain complex, important genes impacting medical phenotypes, but differ from the autosomes in their ploidy and large repetitive regions. To enable technology developers along with research and clinical laboratories to evaluate variant detection on male sex chromosomes X and Y, we create a small variant benchmark set with 111,725 variants for the Genome in a Bottle HG002 reference material. We develop an active evaluation approach to demonstrate the benchmark set reliably identifies errors in challenging genomic regions and across short and long read callsets.
