X-inactivation profile reveals extensive variability in X-linked gene expression in females

TL;DR: A comprehensive X-inactivation profile of the human X chromosome is presented, representing an estimated 95% of assayable genes in fibroblast-based test systems, and suggests a remarkable and previously unsuspected degree of expression heterogeneity among females.
Journal ArticleDOI

The DNA sequence of the human X chromosome

Mark T. Ross, +282 more

TL;DR: This analysis illustrates the autosomal origin of the mammalian sex chromosomes, the stepwise process that led to the progressive loss of recombination between X and Y, and the extent of subsequent degradation of the Y chromosome.
Journal ArticleDOI

Molecular evidence for a relationship between LINE-1 elements and X chromosome inactivation: the Lyon repeat hypothesis.

TL;DR: In this article, the authors show that the X chromosome is enriched 2-fold for L1 repetitive elements, with the greatest enrichment observed for a restricted subset of LINE-1 elements that were active <100 million years ago, providing strong evidence that L1 elements may serve as DNA signals to propagate X inactivation along the chromosome.
Journal ArticleDOI

A first-generation X-inactivation profile of the human X chromosome

TL;DR: The genes that escape inactivation are distributed nonrandomly along the X; 31 of 34 such transcripts map to Xp, implying that the two arms of the X are epigenetically and/or evolutionarily distinct and suggesting that genetic imbalance of Xp may be more severe clinically than imbalance ofXq.
Journal ArticleDOI

Genes that escape from X inactivation.

TL;DR: Differences in the identity and distribution of escape genes between species and tissues suggest a role for these genes in the evolution of sex differences in specific phenotypes and suggests that they may have female-specific roles and be responsible for some of the phenotypes observed in X aneuploidy.
