Esotropia and exotropia could have shared genetic risk factors based on findings that genetif duplications on chromosomes were risk factors for the diseases. Genetic duplications in the second, fourth ...

Scott W. Stuart, MD, MS; Casey H. King, BA; G. Shashidar Pai, MD Such observations emphasize the importance of clarifying the origin of a genetic variation by studying the parents for comparison. The ...

A mother-of-four from Cradley Heath, near Birmingham, has spoken of her two-year-old daughter's diagnosis with an extremely rare disorder, discovered by chance during an unrelated hospital visit.

Down syndrome is a condition in which a person has a fully or partially duplicated copy of chromosome 21. (A chromosome is a structure made up of DNA and proteins found in the nucleus of each cell.) ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

A diagram showing the evolution of vertebrate chromosomes from an invertebrate ancestor through two whole-genome duplication events (shown as starbursts). For simplicity, only one ancestral pair of ...

In a recent study published in the Genes journal, researchers assessed the impact of PARK2 duplication or microdeletion on neurological diseases such as Parkinson's. The Parkinson's disease 2 (PARK2) ...

Plants tend to hoard DNA, not throwing anything out. The extra genes they hold inside can mutate to produce new physical traits. Holding onto the extra genes increases the tempo of evolution for the ...

Cutting-edge technology could one day transform treatment for Down syndrome, as researchers have successfully deleted an extra chromosome in lab-grown cells. Down syndrome - which occurs when a person ...

Spontaneous errors in the earliest phase of cell division may be the reason why so many human embryos fail to develop normally, according to new research. In humans, a fertilized egg is no guarantee ...
