STUDIES of human chromosomes have been greatly facilitated by the development of newer technics, particularly peripheral blood leukocyte culture. 1–3 Many abnormalities have been described, most of ...

Geneticists from Ohio, California and Japan joined forces in a quest to correct a faulty chromosome through cellular reprogramming. Their study, published online today in Nature, used stem cells to ...

I still recall my disappointment one day in 2015. I received the tumor DNA sequencing results for one of my patients, whose cancer had spread from her lungs to her brain. I saw not a single genetic ...

DLGAP5 is proposed as a causal gene related to oocyte meiosis disorder for the first time. It expanded the current spectrum of pathogenic genes responsible for the phenotype of oocyte maturation and ...

The presence of an abnormal number of chromosomes in the genetic profile of early-stage embryos may be far more common - and potentially less threatening - during normal human development than is ...

Berlin, Germany: Aneuploidy (the presence of an abnormal number of chromosomes) in embryos is a major cause of impaired embryo development, leading to conditions such as Down syndrome, as well as to ...

Cytogenetic technologists analyze chromosomes found in biological specimens such as amniotic fluids, bone marrow, and blood to aid in the study, diagnosis, or treatment of genetic diseases.
