UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

Study reveals the impact of X chromosome on brain aging in women. Learn how maternal and paternal X chromosome can influence cognitive abilities.

Women are born with two X chromosomes and inherit one from each parent. But in every cell of their body, just one X chromosome is needed—so the other is randomly inactivated. Some cells use only a ...

A UCSF study reveals that maternal X chromosome expression may accelerate brain aging and cognitive decline. Female mice with ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Patients with Klinefelter and triple X syndromes show an increased prevalence of SLE and Sjögren disease, likely due to the synergistic interaction of the extra X chromosomes.

The X contains more genes related to brain function than does any other chromosome. “The X chromosome may be a treasure trove ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is ...

A new study reveals that the maternal X chromosome may accelerate brain ageing and increase Alzheimer's risk. Experiments on female lab mice showed th ...

Scientists published a full genetic sequence of the genes that make some white campions male, and hope their work could ...
