Examining neurodevelopmental problems in 15q11.2 (BP1‐BP2) copy number variation carriers at ages 9/12 and 18 in a Swedish twin sample

Molecular Genetics & Genomic Medicine, 2023
Background Several copy number variations (CNVs) are associated with increased risk for neurodevelopmental and psychiatric disorders. The CNV 15q11.2 (BP1‐BP2) deletion has been associated with learning difficulties, attention deficit hyperactivity ...

Integration of DNA copy number alterations and transcriptional expression analysis in human gastric cancer. [PDF]

PLoS ONE, 2012
BACKGROUND: Genomic instability with frequent DNA copy number alterations is one of the key hallmarks of carcinogenesis. The chromosomal regions with frequent DNA copy number gain and loss in human gastric cancer are still poorly defined.
