The first is at Glu1273 and the second is at Glu1749, which separately break down lactose into two separate kinds of molecules. [1] At least six mutations (single-nucleotide polymorphisms – SNPs) have been associated with lactase expression. [28] They are all located in a region of the gene MCM6 upstream of LCT.
