Based on #2019nCoV therapy review ( https://f1000research.com/articles/9-72/v2), further evidence was found in the 6 genetic variants associated with higher ratio of ACE2 cells.
This weaponized coronavirus appears to be optimized for binding with the human ACE2 receptor, (1/3) https://twitter.com/RolandBakerIII/status/1228874522171867136

here is a table of races that have the highest concentration of ACE2 receptors:
1. Japanese (Tokyo)
2. Chinese Han (Southern)
3. Vietnamese (Ho Chi Minh)
4. Chinese Han (Beijing)
5. Chinese (Yun people in Yunnan)
Europe and Americans have low risk! (2/3)

The receptor binding domain (RBD) in the spike protein of SARS-CoV and SARS-related coronaviruses is the most variable part of the virus genome. Six residues in the RBD appear to be critical for binding to the human ACE2 receptor and determining host range.(3/3)
