A gradual process of recombination restriction in the evolutionary history of the sex chromosomes in dioecious plants. [PDF]

PLoS Biology, 2005
To help understand the evolution of suppressed recombination between sex chromosomes, and its consequences for evolution of the sequences of Y-linked genes, we have studied four X-Y gene pairs, including one gene not previously characterized, in plants ...

Dosage regulation of the active X chromosome in human triploid cells. [PDF]

PLoS Genetics, 2009
In mammals, dosage compensation is achieved by doubling expression of X-linked genes in both sexes, together with X inactivation in females. Up-regulation of the active X chromosome may be controlled by DNA sequence-based and/or epigenetic mechanisms ...

Localization of the gene for X-linked Alport's syndrome

Kidney International, 1988
X-chromosomal DNA probes defining various polymorphic DNA markers were used to study genetic linkage in three families with Alport's syndrome. With the DXS17 marker, only a single cross-over was observed in 26 informative meioses, and evidence for linkage was also obtained with the DXS11 marker.

Mean Expression of the X-Chromosome is Associated with Neuronal Density. [PDF]

, 2012
peer reviewedBackground: Neurodegenerative diseases are characterized by key features such as loss of neurons, astrocytosis, and microglial activation/proliferation. These changes cause differences in the density of cell types between control and disease

Non-functional immunoglobulin G transcripts in a case of hyper-immunoglobulin M syndrome similar to type 4 [PDF]

, 2004
86% of immunoglobulin G (IgG) heavy-chain gene transcripts were found to be non-functional in the peripheral blood B cells of a patient initially diagnosed with common variable immunodeficiency, who later developed raised IgM, whereas no non-functionally

Masculinization of the X-chromosome in aphid soma and gonads

Peer Community Journal, 2022
Males and females share essentially the same genome but differ in their optimal values for many phenotypic traits, which can result in intra-locus conflict between the sexes.

Bidirectional transcription of a novel chimeric gene mapping to mouse chromosome Yq [PDF]

, 2007
Background The male-specific region of the mouse Y chromosome long arm (MSYq) contains three known highly multi-copy X-Y homologous gene families, Ssty1/2, Sly and Asty.

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.
