Molecular Dissection Using Array Comparative Genomic Hybridization and Clinical Evaluation of An Infertile Male Carrier of An Unbalanced Y;21 Translocation: A Case Report and Review of The Literature [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2016
Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported.

Quantitative analysis of Y-Chromosome gene expression across 36 human tissues

open access: yesGenome Research, 2020
Little is known about how human Y-Chromosome gene expression directly contributes to differences between XX (female) and XY (male) individuals in nonreproductive tissues.

The outcomes of fetal cell microchimerism in the mother

open access: yesBiomedical Research Journal, 2021
The presence of small quantities of genetically heterogeneous cells in an organism is known as microchimerism. Fetal microchimerism is the presence of small quantities of fetal cells in the maternal system during and after pregnancy.

The degeneration of Y chromosomes [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Y chromosomes are genetically degenerate, having lost most of the active genes that were present in their ancestors. The causes of this degeneration have attracted much attention from evolutionary theorists. Four major theories are reviewed here: Muller's ratchet, background selection, the Hill–Robertson effect with weak selection, and the ‘hitchhiking’

The Dutch Y-chromosomal landscape [PDF]

open access: yesEuropean Journal of Human Genetics, 2019
AbstractPrevious studies indicated existing, albeit limited, genetic-geographic population substructure in the Dutch population based on genome-wide data and a lack of this for mitochondrial SNP based data. Despite the aforementioned studies, Y-chromosomal SNP data from the Netherlands remain scarce and do not cover the territory of the Netherlands ...

Assessment of Correlation between Androgen Receptor CAG Repeat Length and Infertility in Infertile Men Living in Khuzestan, Iran [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2015
Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (N- TAD).

Effective Model of Loop Extrusion Predicts Chromosomal Domains [PDF]

open access: yesPhys. Rev. E 102, 032414 (2020), 2020
An active loop-extrusion mechanism is regarded as the main out--of--equilibrium mechanism responsible for the structuring of megabase-sized domains in chromosomes. We developed a model to study the dynamics of the chromosome fibre by solving the kinetic equations associated with the motion of the extruder.

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]

open access: yes, 2006
We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

The Origin of a New Sex Chromosome by Introgression between Two Stickleback Fishes. [PDF]

open access: yes, 2019
Introgression is increasingly recognized as a source of genetic diversity that fuels adaptation. Its role in the evolution of sex chromosomes, however, is not well known. Here, we confirm the hypothesis that the Y chromosome in the ninespine stickleback,

Y-chromosome evolution: emerging insights into processes of Y-chromosome degeneration [PDF]

open access: yesNature Reviews Genetics, 2013
The human Y chromosome is intriguing not only because it harbours the master-switch gene that determines gender but also because of its unusual evolutionary history. The Y chromosome evolved from an autosome, and its evolution has been characterized by massive gene decay.
