Large inverted duplications in the human genome form via a fold-back mechanism. [PDF]
Inverted duplications are a common type of copy number variation (CNV) in germline and somatic genomes. Large duplications that include many genes can lead to both neurodevelopmental phenotypes in children and gene amplifications in tumors.

Polyploidization, or whole‐genome duplication, leads to gene expression changes that drive the evolution of many plants and some animals. However, the role of the dosage effect on gene expression changes following genome duplication remains unclear. Here,

Background The great diversity in plant genome size and chromosome number is partly due to polyploidization (i.e. genome doubling events). The differences in genome size and chromosome number among diploid plant species can be a window into the ...

Example of CNV merging on a chromosome X duplication.
A. Entire duplication of chromosome X. CovCopCan detects six CNV areas without the merging CNV algorithm. B. By using the merging CNV algorithm, the duplication detected includes all of chromosome X, although some amplicons appear as neutral (grey dots).

Functional and molecular effects of chromosome 21 trisomy [PDF]
Down Syndrome (DS) is the most frequent autosomal aneuploidy that is compatible with post-natal life. The DS phenotype has been attributed to overexpression of chromosome 21 (Hsa21) genes.

Phenotypic and Cytogenetic Variety of Pure Partial Trisomy [PDF]
Duplications of chromosome 16p are often the products of unbalanced maternal reciprocal translocations and consequently the phenotype of patients is not typical of pure partial trisomy 16p.

Insertional translocations in which a duplicated region of one chromosome is inserted into another chromosome are very rare. We report a 16.5-year-old girl with a terminal duplication at 9q34.3 of paternal origin inserted into 19q13.4.

An Adolescent with a Rare De Novo Distal Trisomy 6p and Distal Monosomy 6q Chromosomal Combination
We report on a 12-year-old female with both a partial duplication and deletion involving chromosome 6. The duplication involves 6p25.3p24.3 (7.585 Mb) while the deletion includes 6q27q27 (6.244 Mb).

Segmental duplication is a major structural variation that occurs in chromosomes. Duplication leads to the production of gene copies with increased numbers of related repeat segments, causing the global genome to be in a state of imbalance.
