Notes

Notes

Deletion of both copies of this gene alters testosterone metabolism making steroid use undetectable. The first page of this thesis claims that the deletion allele has a frequency of 4.8% in Swedes but is completely absent in Koreans. While its abstract claims "it is a common polymorphism with an allele frequency of 29 % in Swedes and 78 % in Koreans."
