Researchers mapped Y chromosome loss across thousands of individual cells from human cancers, with disturbing results.

X chromosome inactivation, a high percentage of genes escaping X chromosome inactivation, female mosaicism and heterogeneity in X chromosome inactivation patterns are likely to contribute to ...

The degree of overt mosaicism is not necessarily consistent with the amount of genetic dissimilarity. Some mosaics that show no obvious cellular variance may be distinguished by chromosome ...

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop.

Hundreds of thousands of chromosome studies are performed each year on peripheral lymphocytes, skin fibroblasts, amniotic fluid cells and chorionic villus tissue, and rates of mosaicism for ...

The Y chromosome, which plays a critical role in male development, is losing genetic material and may disappear in about 11 million years. Separately, a major 2017 study revealed that sperm counts in ...

By the age of 70, about 40% of men have lost the Y chromosome in at least some of their white blood cells. This condition, ...

Mosaic Loss of Y (LOY): A Prevalent Phenomenon Long before the Y chromosome potentially vanishes from the human species, many men are already experiencing its loss within certain cells. Commencing ...
