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

Mutations in the X chromosome often cause intellectual disability, and women born with just one X chromosome (a diagnosis known as Turner Syndrome), can have cognitive impairments. X chromosomes, some ...

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

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.

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

What causes it? “Fragile X syndrome is caused by a change in the FMR1 gene, and the FMR1 gene is located on the X chromosome,” explains Richardson. “This abnormal gene, which can be passed ...

In these cases, Down syndrome is caused by a translocation of chromosomes 15 and 21 (Figure 3), in which the long arms of two acrocentric chromosomes are translocated to produce a single long ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. The X chromosome passed from mom to ...

DiGeorge syndrome, a 22q11.2 deletion syndrome, is caused when a small portion of chromosome 22 is missing. The condition can occur in individuals born from a parent with the dominant contiguous ...
