What gene causes no body odor?
ABCC11: the “no body odor gene”
Genetic variants that cause a loss of function of the ABCC11 gene are very common among East Asian populations (80-90% of the population). In other population groups, it is rare to have no body odor. In fact, only around 2% of Caucasians carry the 'no body odor' version of the gene.
What ethnicity has the ABCC11 gene?

Eccrine gland sweat lacks the fats and other compounds that can smell when broken down by bacteria. Therefore, it's less likely to produce a smell.

Two percent of people carry an unusual form of a specific gene (ABCC11) that means their armpits never smell. The finding came from new research involving 6,495 women who are enrolled in the Children of the 90s study at the University of Bristol, England, and was published in the Journal of Investigative Dermatology.
Do I have the ABCC11 gene?
The gene variant is known as ABCC11 and the study authors said that the consistency of earwax is a good indication of those who have it. People who have dry earwax as opposed to sticky earwax are highly likely to have the ABCC11 variant and therefore do not produce under arm body odour.
Do Koreans smell armpits?
