Why does the X chromosome lag behind autosomes in GWAS findings?

PLoS Genetics, 2023
The X-chromosome is among the largest human chromosomes. It differs from autosomes by a number of important features including hemizygosity in males, an almost complete inactivation of one copy in females, and unique patterns of recombination.

Mosaicism for r(X) and der(X)del(X)(p11.23)dup(X)(p11.21p11.22) provides insight into the possible mechanism of rearrangement

Molecular Cytogenetics, 2008
We report a patient with a unique and complex cytogenetic abnormality involving mosaicism for a small ring X and deleted Xp derivative chromosome with tandem duplication at the break point. The patient presented with failure to thrive, muscular hypotonia,

Identification of candidate novel production variants on the Bos taurus chromosome X

Journal of Dairy Science, 2023
: Chromosome X is often excluded from bovine genetic studies due to complications caused by the sex specific nature of the chromosome. As chromosome X is the second largest cattle chromosome and makes up approximately 6% of the female genome, finding ...

X Chromosome of Female Cells Shows Dynamic Changes in Status during Human Somatic Cell Reprogramming

Stem Cell Reports, 2014
Induced pluripotent stem cells (iPSCs) acquire embryonic stem cell (ESC)-like epigenetic states, including the X chromosome. Previous studies reported that human iPSCs retain the inactive X chromosome of parental cells, or acquire two active X ...

The probability to initiate X chromosome inactivation is determined by the X to autosomal ratio and X chromosome specific allelic properties.

PLoS ONE, 2009
BackgroundIn female mammalian cells, random X chromosome inactivation (XCI) equalizes the dosage of X-encoded gene products to that in male cells. XCI is a stochastic process, in which each X chromosome has a probability to be inactivated. To obtain more

Who’s afraid of the X? Incorporating the X and Y chromosomes into the analysis of DNA methylation array data

Epigenetics & Chromatin, 2023
Background Many human disease phenotypes manifest differently by sex, making the development of methods for incorporating X and Y-chromosome data into analyses vital.

European Medical Journal, 2017
Many autoimmune diseases, such as lupus and Sjögren’s syndrome, have a female bias and adult onset. One possible explanation for this bias is disruption of the inactive X chromosome, which is a major epigenetic feature in female cells. Indeed, only one X

The X chromosome and sex-specific effects in infectious disease susceptibility

Human Genomics, 2019
The X chromosome and X-linked variants have largely been ignored in genome-wide and candidate association studies of infectious diseases due to the complexity of statistical analysis of the X chromosome.

An additional X chromosome

South African Medical Journal, 2014
A 35-year-old man presented with symmetrical inflammatory polyarthritis of the small and large joints and associated early-morning stiffness. He was assessed as having features in keeping with Klinefelter’s syndrome. It is evident from the literature that there is a relationship between Klinefelter’s syndrome and developing rheumatic conditions.
