}}{{PMID|18334593}} Deletion of both copies of this gene alters testosterone metabolism making steroid use undetectable. 

The first page of this [http://diss.kib.ki.se/2007/978-91-7357-397-9/thesis.pdf thesis] claims that the deletion allele has a frequency of 4.8% in Swedes but is completely absent in Koreans. While its [http://diss.kib.ki.se/2007/978-91-7357-397-9/ abstract] claims "it is a common polymorphism with an allele frequency of 29 % in Swedes and 78 % in Koreans."
