The following is an excerpt.
No two people are alike, due to the subtly different ways our genomes are expressed. But sometimes these biological differences lead to genetic mutations that are extremely rare, and sometimes debilitating. Historically, many people suffering from these mutations were labeled monsters or freaks — but today, we know they are simply part of the broad spectrum of genetic variations in our species. Here are 10 of the most unusual genetic mutations we’ve identified in humans.
1. Progeria
This genetic disorder is as rare as it is severe. The classic form of the disease, called Hutchinson-Gilford Progeria, causes accelerated aging.
