[PMID 16444273] This SNP determines wet vs dry earwax as well as sweat production, and it is also associated with lipid secretion. It is commonly (T;T) for East Asians and (C;C) for Europeans and Africans.
[PMID 23325016] A study of deodorant usage in a large (17,000+) population showed that rs17822931(T;T) individuals were at least 5-fold less likely to use deodorant, consistent with them being "genotypically nonodorous". Although not statistically significant, there was some evidence for a heterozygote effect, implying that individuals with a (C;C) genotype for this SNP were likely to use deodorant at a higher frequency than (C;T) genotypes.
