For reference, a normal human X chromosome is also shown (X). For the X;22 (case 68) and X;14 (case 4) translocations involving band Xq13, the autosomal protion of the translocation chromosomes is ...

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 ...

C.L. (J.H.H. 942087) was born on October 1. 1957, prematurely, weighing 1.9 kg. (4 pounds, 5 ounces). The father was 40, and the mother 39 years old at that time. The mother's 1st pregnancy terminated ...

Abnormal chromosomes can present challenges during cell division. A new study shines light on how this dysfunctional process may produce mutational patterns commonly found in cancer cells. Every time ...

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 ...

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 ...

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 ...

A tension-sensitive "fail safe" protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes, researchers from the University of Washington and ...

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 ...

Chronic myeloid leukemia (CML) is a rare blood cancer that develops in the bone marrow. Karyotyping is a genetic technique doctors use to diagnose CML and choose more effective treatments. Karyotyping ...
