Also known as "C/T(-13910)" or just 13910T, and located in the MCM6 gene but with influence on the lactase LCT gene, rs4988235 is one of two SNPs that is associated with the primary haplotype associated with hypolactasia, more commonly known as lactose intolerance in European Caucasian populations. [PMID 11788828], [PMID 15114531]
In populations of sub-Saharan Africans, though, the rs4988235(T) allele is so rare that it's unlikely to be predictive of lactase persistence, and other SNPs are predictive instead. [PMID 15106124, PMID 17159977]
