Notes
Some news linked it to lactose intolerance: * Screening of variants for lactase persistence/non-persistence in populations from South Africa and Ghana. * Association of the European lactase persistence variant (LCT-13910 C>T polymorphism) with obesity in the Canary Islands. * Several different lactase persistence associated alleles and high diversity of the lactase gene in the admixed Brazilian population. It is however a typo: “There was a typographical error in the rs number in the Abstract and Introduction. The correct rs number is rs4988235.”plosone.org
