This is probably moderately more interesting to me a (fraternal) twin, but it’s still unexpected.

“The presumption has always been that identical twins are identical down to their DNA,” said Carl Bruder, Ph.D. and Jan Dumanski, Ph.D., of UAB’s Department of Genetics and the study’s lead authors. “That’s mostly true, but our findings suggest that there are small, subtle differences due to [copy number variation]. Those differences may point the way to better understanding of genetic diseases when we study so-called discordant monozygotic twins….a pair of twins where one twin has a disorder and the other does not.”
