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.

What is the stinky armpit gene?

Although FMO3 gene variants account for most cases of trimethylaminuria, the condition can also be caused by other factors. The strong body odor may result from an excess of certain chemical compounds in the diet or from an abnormal increase in bacteria that produce trimethylamine in the digestive system.

Scientists believe that the mutation reached high frequencies in Northeast Eurasia and, following a population increase, expanded over the rest of the continent.

Is ABCC11 dominant or recessive?

A recent study6 showed that a single-nucleotide polymorphism, (SNP) 538 G β†’ A (rs17822931), in the adenosine triphosphate (ATP)-binding cassette, sub-family C11 (ABCC11) gene is responsible for the earwax phenotypes: G for the dominant (wet) allele and A for the recessive (dry) allele.

Does Japanese have body odor?

It looks a bit like a toothbrush, with a scoop replacing the brush portion.

Is there DNA in earwax?

Why do East Asians have dry earwax?

The scientists studied all Asians: East, South, Central, ect. The study found that 85-95% of East Asians (Chinese, Koreans, and Japanese) had the non-stinky/less sweat gland version of the gene, and therefore more likely to have dry earwax.

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.
