|(C;C)||2.5||likely to be lactose intolerant as an adult|
|(C;T)||1.1||likely to be able to digest milk as an adult|
|(T;T)||1.1||can digest milk|
In these populations, the rs4988235(T) allele is both the more common allele and the one associated with lactase persistence; individuals who are rs4988235(C;C) are likely to be lactose intolerant.
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]
