What race has the most ABCC11 gene?

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.

What ethnicity has the ABCC11 gene?

East Asian and Native American people were already known to have a form of the ABCC11 gene that causes the dry type of earwax and produces less underarm body order, compared with other ethnicities.

What ethnicity does not have body odor?

While only 2 percent of Europeans lack the genes for smelly armpits, most East Asians and almost all Koreans lack this gene, Day told LiveScience.

How common is the ABCC11 gene?

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 ethnicity has dry earwax?

Dry earwax is found in 80-95% of people of East Asian descent, but in less than 3% of people of European or African descent. This distinct geographic distribution of earwax type provides clues about early human migration patterns.

ASIAN EARWAX IS TOTALLY DIFFERENT!?!!

What races have wet earwax?

Earwax comes in two types, wet and dry. The wet form predominates in Africa and Europe, where 97 percent or more of the people have it, and the dry form among East Asians, while populations of Southern and Central Asia are roughly half and half.

Is ABCC11 dominant or recessive?

A recent study⁶ showed that a single-nucleotide polymorphism, (SNP) 538 G → 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.

Who lacks the ABCC11 gene?

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.

Does body odor depend on ethnicity?

One large study failed to find any significant differences across ethnicity in residual compounds on the skin, including those located in sweat. If there were observed ethnic variants in skin odor, one would find sources to be much more likely in diet, hygiene, microbiome, and other environmental factors.

Why do Koreans lack ABCC11?

But it turns out that Koreans are "genetically mutated" to have less of a sweating problem than others, according to research. The University of Bristol research suggested only 0.006 percent of the Korean population have the ABCC11 gene, a major culprit behind the odor problem.

Which ethnicity has the most body Odour?

Although there is some controversy on the subject of "racial" variation in body odor, it is determined that African blacks probably produce the greatest amount of apocrine sweat, which is the known substrate for axillary odor.

Why do East Asians not sweat?

Relevant paragraph from Wikipedia from the article on body odor below, but the TL;DR is that there's a gene called ABCC11 that is non-functional in 80 to 95 percent of East Asians. That allele determines both apocrine sweat gland size and activity, concentration of protein in apocrine sweat, and, oddly, wet-type vs.

How do I know if 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.

Why do some Asians not wear deodorant?

The frequencies of the A and G alleles vary markedly across different ethnic groups. The A allele is very common in East Asians, and as expected, most people in this population don't need to use deodorant. And so they don't use it—it's estimated that only 7% of North East Asians regularly use deodorant.

What chromosome is ABCC11 on?

The ABCC11 gene is located on human chromosome 16q12. 1 [6–8]. ABCC11, also known as multidrug resistance-associated protein 8 (MRP8), is a full ABC transporter with a total of 12 putative transmembrane domains and two ATP-binding cassettes [9].

Do Japanese people have ABCC11?

Recently, genetic variants of ABCC4 (OMIM: 605250) and ABCC11 (OMIM: 607040), which are particularly common in the Japanese population, were suggested as possible genetic susceptibility factors for the development of SMON.

What is the stinky armpit gene?

The underarm body odor has been linked to a gene called ABCC11, which encodes a protein that transports molecules across cellular membranes, including molecules in the sweat. If the ABCC11 gene is non-functional, sweat molecules are unable to cross the membrane barrier to reach the armpit.

Is ABCC11 gene important?

A functional ABCC11 allele is essential in the biochemical formation of human axillary odor. J Invest Dermatol 130, 529–540 (2010). Preti, G. & Leyden, J. J. Genetic influences on human body odor: from genes to the axillae.

Is dry or wet earwax better?

Healthy dry earwax does fall out of the ear better than wet earwax, and it is effective at preventing ear infections. However, it's still important to keep your ears clean because dry earwax flakes can build up over time and cause a blockage.

What color is black people's ear wax?

Also mentioned in the study: "Africans" have "wet, yellowish-brown wax," and Native Americans — similar to East Asian folks — typically have "dry, white wax." "The difference between [the earwax] is caused by a single gene in the genome.

Do Japanese people not have earwax?

This study confirmed that the Japanese population has two distinct earwax types. The genotype detection rate among 1963 nail samples was 99.6%, and the average allele-A frequency (f^A) among 47 prefectures was 0.878.

What gene is Korean ear wax?

The variation between ear wax in ethnicities around the world are specifically due to the ABCC11 gene alleles. It is believed the allele originated in ancient East Asian population.

How do I make sure my armpits don't smell?

Is smelly armpit part of puberty?

For most kids, body odor is part of growing up. Kids start to have body odor around the time puberty starts and hormones change. Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later.

Why do Europeans not use deodorant?

For one, they may not believe that it is necessary to do so. They may also believe that underarm deodorant can be harmful to the body, as it can be absorbed into the skin. Additionally, some Europeans may simply prefer not to wear deodorant, as it can be uncomfortable or inconvenient.
