Genes that escape from X‐chromosome inactivation: Potential contributors to Klinefelter syndrome
One of the two X chromosomes in females is epigenetically inactivated, thereby compensating for the dosage difference in X‐linked genes between XX females and XY males.

X-Chromosome Inactivation: A Crossroads Between Chromosome Architecture and Gene Regulation.
In somatic nuclei of female therian mammals, the two X chromosomes display very different chromatin states: One X is typically euchromatic and transcriptionally active, and the other is mostly silent and forms a cytologically detectable heterochromatic ...

Escape from X chromosome inactivation and female bias of autoimmune diseases
Generally, autoimmune diseases are more prevalent in females than males. Various predisposing factors, including female sex hormones, X chromosome genes, and the microbiome have been implicated in the female bias of autoimmune diseases.

Artificial escape from XCI by DNA methylation editing of the CDKL5 gene. [PDF]
A significant number of X-linked genes escape from X chromosome inactivation and are associated with a distinct epigenetic signature. One epigenetic modification that strongly correlates with X-escape is reduced DNA methylation in promoter regions. Here,

Demasculinization of the Anopheles gambiae X chromosome [PDF]
Background: In a number of organisms sex-biased genes are non-randomly distributed between autosomes and the shared sex chromosome X (or Z). Studies on Anopheles gambiae have produced conflicting results regarding the underrepresentation of male-biased ...

Hormad1 mutation disrupts synaptonemal complex formation, recombination, and chromosome segregation in mammalian meiosis [PDF]
Meiosis is unique to germ cells and essential for reproduction. During the first meiotic division, homologous chromosomes pair, recombine, and form chiasmata.

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

Altered X-chromosome inactivation in T cells may promote sex-biased autoimmune diseases.
Systemic lupus erythematosus (SLE) is an autoimmune disorder that predominantly affects women and is driven by autoreactive T cell-mediated inflammation.

Allele-specific expression analysis does not support sex chromosome inactivation on the chicken Z chromosome [PDF]
Heterogametic sex chromosomes have evolved many times independently, and in many cases the loss of functional genes from the sex-limited Y or W chromosome leaves only one functional gene copy on the corresponding X or Z chromosome in the heterogametic ...

Systematic allelic analysis defines the interplay of key pathways in X chromosome inactivation
Xist RNA, the master regulator of X chromosome inactivation, acts in cis to induce chromosome-wide silencing. Whilst recent studies have defined candidate silencing factors, their relative contribution to repressing different genes, and their ...
