Whenever a cell divides, it has to split its chromosomes perfectly between two daughter cells, and even a single mistake can be disastrous. Now, researchers from Japan have found that one of the key ...

A chromosome-mapping study and literature synthesis found variation in the number, position and synteny of 5S and 35S rDNA ...

Japanese researchers used CRISPR-Cas9 to remove the extra chromosome 21 from cells in a lab. It's a real breakthrough — but not a Down syndrome cure, and not a new 2026 treatment.

A seven-year case study of a prenatal 19p13.3–p13.2 duplication found persistent developmental and growth problems alongside ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

Research suggests X and Y chromosomes may influence aging and disease risk, beyond determining biological sex.

Prognosis is poor for tumours with Y-chromosome loss. Examining the interplay between cancer and immune cells sheds light on potential mechanisms. Read the paper: Concurrent loss of the Y chromosome ...

Single deletions may be asymptomatic, but 'multiple deletions lead to infertility'—Mouse study with comprehensive deletion of ...

Results provide framework for uncovering regulatory variants in other X chromosome neurodevelopmental genes that may ...

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...
