Identical twins share all their genes; fraternal twins share no more genes than normal siblings do, but they get exposed to the same environment in the womb and at home during infancy.

Although bacteria have a seemingly limitless capacity to alter their genes by swapping bits of DNA between strains, this mechanism doesn't seem enough to account for the swift pace of change and the high variability of E. coli and other strains.Thomas Cebula of the U.S. Food and Drug Administration (FDA) wondered if this rapid evolution is being driven by microbes capable of much faster - than - normal variation.

So you got to think that, you know, you could have perhaps hybrids being created, but if those hybrids do not breed back into the parent populations, because they look a bit different to normal, their combination [of] features, those genes will never penetrate the parent populations.

The cells with the normal gene grew significantly longer dendrites — the portions of the cell that reach out to receive nerve impulses — than did neurons with the mutated gene, the team reports 14 October in Science.

When studying how normal cells change into cancer cells, dos Santos and other cancer researchers pay close attention to gene expression.

The reason has been a mystery, but some researchers suspect it has to do with one or more of the genes on chromosome 21, which people with Down syndrome have three copies of instead of the normal two.

HD genes with CAG lengths between 27 - 35, which do not result in HD symptoms, but are longer than normal.

What WAVE has done might get around these issues because their two drugs specifically target the mutant gene, leaving the normal copy alone.

The Ionis ASO doesn't distinguish between RNA coming from the normal and mutant copy of the gene, so it lowers the amount of both the normal and mutant protein.

Potential therapies targeting this synthetic lethal target will have dramatically reduced toxicity since normal cells do not rely on these genes.

Meanwhile, the normal copy of the gene produces a protein that does useful stuff and doesn't cause harm.

I have seen many patients over the years with Hashimoto's whose health care practitioners have told them they can eat gluten because they had a normal gluten antibody test (meaning there is no sensitivity) or they did not have the gene for gluten sensitivity.

They successfully identified the gene causing rcd - 1 in Irish Setters, and developed a blood test which can identify dogs with normal DNA, dogs which are carriers, and dogs which are genetically affected with PRA, even though they do not yet show signs.

This area becomes a bit more gray, because while there is a very good argument for not breeding close relatives of affected and carrier dogs, we also can not afford to eliminate all dogs in the gene pool who meet this criterion — to do so would risk further constriction of the gene pool to the point where the remaining «epilepsy - free» individuals might have higher - than - normal frequency for genes that contribute to some other genetic disorder.

There may be other causes of this condition in dogs and a normal result does not exclude a different mutation in this gene or any other gene that may result in a similar genetic disease or trait.
