Latest Chromosome 21 Stories
Although doctors have long known that people with Down syndrome have a heightened risk of developing acute lymphoblastic leukemia (ALL) during childhood, they haven't been able to explain why.
The first evidence that the underlying genetic defect responsible for trisomy 21, also known as Down syndrome, can be suppressed in laboratory cultures of patient-derived stem cells was presented today (Oct. 22) at the American Society of Human Genetics 2013 annual meeting in Boston.
Scientists at the University of Massachusetts Medical School have made a huge breakthrough in our understanding of Down's syndrome.
Geneticists from the University of Washington have successfully removed the extra chromosome 21 from cells derived from a person with Down syndrome.
A healthy genome is characterized by 23 pairs of chromosomes, and even a small change in this structure — such as an extra copy of a single chromosome — can lead to severe physical impairment.
A novel study involving fruit flies and mice has allowed biologists to identify two critical genes responsible for congenital heart defects in individuals with Down syndrome.
A protein associated with Alzheimerâ€™s disease clogs several motors of the cell transport machinery critical for normal cell division, leading to defective neurons that may contribute to the memory-robbing disease.
