**Angiotensin-converting enzyme 2 (ACE2)**

***What chromosome is ACE2 on?***
 In humans (Homo sapiens) it is located on the chromosome X

***How many exons does this gene have?***
18 exons but new research have predicted 8 novel exons that might participate in alternative splicing.

***Briefly describe how the gene works.***
The peptidyl dipeptidase A, carboxycathepsin (ACE2) cleaves the C-terminal dipeptide from angiotensin I to create the vasoconstrictor peptide, angiotensin II (ACE2). ACE2 gene expession can be done in multiple tissues.

***What diseases are caused by mutations in the gene?***
Decreased expression of ACE2 is associated with cardiomiopahyes, atherosclerosis, chronic Kidney disease, cardiovascular problems, and severe acute respiratory syndrome.
