1q21.1 deletion carriers have been associated more with schizophrenia than duplications and duplication carriers have been associated more with autism spectrum disorders.
After mapping bZIPs onto the genomic scaffolds, many tandem duplications and duplications within/between scaffold(s) were inferred (indicated with asterisks in Figure 3).
Other kinds of gene duplication at small scales, such as tandem duplication, segmental duplication, and duplicative retroposition, have also continually enlarged the pool of duplicated genes.
Several gene duplication modes drive the evolution of protein-coding gene families, including WGD or segmental duplication, tandem duplication, and rearrangements at the gene and chromosomal level [ 38].
Three principal evolutionary patterns were attributed to gene duplications: segmental duplication, tandem duplication, and transposition events such as retroposition and replicative transposition [ 71].
Segmental duplication, tandem duplication, and transposition events such as retro- and replicative transposition are the three main forces that drive the expansion of gene families [ 41, 42].
Segmental duplication, tandem duplication and transposition events such as retroposition and replicative transposition are the main reasons for gene family expansion [ 22].
Segmental duplication, tandem duplication, and transposition events, such as retroposition and replicative transposition [ 23], are considered to represent three principal evolutionary patterns.
Gene duplication, including tandem duplication, segmental duplication and genome duplication, continues to be a pervasive process and contributes to biological novelty in evolution [ 39, 40].
Whole genome duplication, segmental duplication and complex transcriptional regulation contributed to the gene expansion and mRNA diversity of the MaSODs.
