Glycine encephalopathy, which is also known as nonketotic hyperglycinemia or NKH, is a genetic disorder characterized by abnormally high levels of a molecule called glycine.bout 80 percent of cases of glycine encephalopathy result from mutations in the GLDC gene, while AMT mutations cause 10 percent to 15 percent of all cases. In a small percentage of affected individuals, the cause of this condition is unknown.
The Elements: 2009 y There are 91 naturally occurring elements (but it depends on how you count them). y The heaviest element that occurs in large quantity is uranium (atomic number 92). You can mine it like gold.
There are a couple of ways to answer this. 1  The element with the most collective mass in the universe is: Hydrogen (75%) 2  The element with the most collective mass on earth is Oxygen (about 46%) 3  The most massive atom that is stable is lead. 4  The most massive naturally occurring element that we know of is Uranium with an AMU of 238. There might be some wiggle room here. Some think there might be one of two that are bigger. But anything above Uranium was artificially made or lasts only a very brief period of time.
