Autosomes are any chromosome other than a sex chromosome. Humans have 22 pairs of autosomes.
This rare genetic condition can theoretically affect patients at any age but symptoms are more often observed in childhood and even uncommonly during the first days of life.
New research published Online First in The Lancet suggests that a high proportion of severe intellectual disability results from genetic causes that are not inherited. These findings are good news for parents, indicating a low risk of passing on the disorder to further children.
Is it a boy or a girl? Expecting parents may be accustomed to this question, but contrary to what they may think, the answer doesn't depend solely on their child's sex chromosomes.
In the first evolutionary study of the chromosome associated with being female, University of California, Berkeley, biologist Doris Bachtrog and her colleagues show that the history of the X chromosome is every bit as interesting as the much-studied, male-determining Y chromosome, and offers important clues to the origins and benefits of sexual reproduction.
The Centre for Addiction and Mental Health (CAMH) has discovered a new form of intellectual disability involving mental retardation (MR) along with the eye defect retinitis pigmentosa (RP).
In animals with separate sexes, embryos commit to becoming male or female at an early stage.
Researchers at the University of Chicago have discovered there is extensive gene “traffic”—the process of genes leaving and arriving on the chromosome—on the mammalian X chromosome. They also have overturned a conventional theory about how genes evolved on the sex chromosome.
