The MCM6 gene contains a regulatory element that modulates the expression of the LCT gene. The LCT gene encodes lactase.
Regulatory gene regions are specific nucleotide sequences that act to control the expression of a gene and genes found in the same genomic region (linkage group).
In this case, the MCM6 gene encodes for a helicase and contains a regulatory region in one of its introns that modulates the expression of the LTC gene.
The LTC gene encodes a fundamental enzyme in the metabolism of lactose known as lactase.
