Tandem duplication of a genomic region encoding glutathione S-transferase epsilon-2 and -4 genes in DDT-resistant Anopheles stephensi strain from India

open access: yesScientific Reports, 2022
The glutathione S-transferases (GST) genes are a multigene family of enzymes involved in the metabolism of endogenous and xenobiotic compounds by catalysing the conjugation of the reduced form of glutathione to the substrate.

The gain and loss of genes during 600 million years of vertebrate evolution [PDF]

open access: yes, 2006
BACKGROUND: Gene duplication is assumed to have played a crucial role in the evolution of vertebrate organisms. Apart from a continuous mode of duplication, two or three whole genome duplication events have been proposed during the evolution of ...

Duplicability of self-interacting human genes [PDF]

open access: yesBMC Evolutionary Biology, 2010
Abstract Background There is increasing interest in the evolution of protein-protein interactions because this should ultimately be informative of the patterns of evolution of new protein functions within the cell. One model proposes that the evolution of new protein-protein interactions and protein complexes proceeds

Multi-faceted analysis provides little evidence for recurrent whole-genome duplications during hexapod evolution

open access: yesBMC Biology, 2020
Background Gene duplication events play an important role in the evolution and adaptation of organisms. Duplicated genes can arise through different mechanisms, including whole-genome duplications (WGDs).

Two Major Paths of Gene-Duplicates Evolution [PDF]

open access: yesarXiv, 2004
Evolving genomes increase a number of their genes by gene duplications. To escape degradation in a functionless pseudogene, any gene duplicate needs to be guarded by negative (purifying) selection from otherwise inevitable fixation of degenerative mutations. In the present study we focus on the evolutionary stage at which new duplicates come under such

Simulating Evolution by Gene Duplication [PDF]

open access: yesGenetics, 1987
ABSTRACT By considering the recent finding that unequal crossing over and other molecular interactions are contributing to the evolution of multigene families, a model of the origin of repetitive genes was studied by Monte Carlo simulations.

Exonic duplication of the OTC gene by a complex rearrangement that likely occurred via a replication-based mechanism: a case report

open access: yesBMC Medical Genetics, 2018
Background Ornithine transcarbamylase deficiency (OTCD) is an X-linked recessive disorder involving a defect in the urea cycle caused by OTC gene mutations.

Reconciliation of Gene and Species Trees With Polytomies [PDF]

open access: yesarXiv, 2012
Motivation: Millions of genes in the modern species belong to only thousands of `gene families'. A gene family includes instances of the same gene in different species (orthologs) and duplicate genes in the same species (paralogs). Genes are gained and lost during evolution.

A familial chromosomal complex rearrangement confirms RUNX1T1 as a causative gene for intellectual disability and suggests that 1p22.1p21.3 duplication is likely benign

open access: yesMolecular Cytogenetics, 2019
Background Complex chromosomal rearrangements are constitutive structural aberrations involving three or more breaks. They can be balanced or unbalanced and result in different outcomes, depending on deletion/duplication of genomic material, gene ...

On the Evolutionary Fate of Mutant Allele at Duplicate Loci: a Theoretical and Simulation Study [PDF]

open access: yesarXiv, 2010
Gene duplications are one of major primary driving forces for evolutionary novelty. We took population genetics models of genes duplicate to study how evolutionary forces acting during the fixation of mutant allele at duplicate loci. We study the fixation time of mutant allele at duplicate loci under double null recessive model (DNR) and ...
