We may have complex brains but evolution hasn’t dealt us the best hand when it comes to genetics.

Researchers identified an unusual genetic mutation in orange domestic cats that has not been found in any other animal, according to a new study.

A Stanford-led study has identified a mutation on the X chromosome that causes orange fur in cats. The mutation switches on the normally silent <i>Arhgap36</i> gene in pigment cells, blocking ...

An advanced genomic analysis of a multigenerational family is providing new knowledge about genetic mutations and their transmission, both the variants that are inherited and those that arise anew.

Scientists at UC San Diego find that gene expression is linked to gene mutations and may be caused by them. That could make efforts to slow the aging process a lot more challenging.

X chromosome mutations can cause intellectual disability, and the X chromosome is thought to be crucial to brain health. Since many genes that are related to the brain are on the X chromosome, the ...

X-chromosome inactivation may reduce autism risk In mice, the pattern of X-chromosome inactivation in female brains altered the effect of a mutation linked to the disorder. Peer-Reviewed ...

Previous work by the laboratory identified a "genomic spellchecker," a DNA repair mechanism devoted to reducing mutation risks in key parts of human chromosomes.

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...
