For years I have been reading and hearing DNA tests are 100% accurate, test results are absolute and can’t be wrong. I believed this until last night, I saw a television program She's Her Own Twin Two Woman Don't Match Their Kid's DNA It's a Medical Mystery.
A woman couldn't prove her children were her own through a simple DNA test. She fought in court to keep her children. Finally, doctors told her she had a rare disorder, chimera.
It's a rare condition called chimerism, with only 30 documented cases worldwide. In Greek mythology, "chimera" means a monster: part goat, part lion, part snake.
In human biology, a chimera is an organism with at least two genetically distinct types of cells -- or, in other words, someone meant to be a twin. But while in the mother's womb, two fertilized eggs fuse, becoming one fetus that carries two distinct genetic codes -- two separate strands of DNA.
The twin is invisible, but for chimeras the twin lives microscopically inside the body as DNA.
Do you think this discovery will decrease the reliability of DNA tests?
Do you think there could be other genetic abnormalities that may cause DNA tests to be inaccurate?
I copied and added the full story from ABC.com in my comments if anyone would like to read it.
Have a great day!
