Quick test description:
The test examines two variants, c.-13910T/C (rs4988235) and c.-22018A/G (rs182549), in the regulatory region of the LCT gene, which codes for the lactase enzyme that is essential for digesting milk sugar (lactose). Adults with the CC/GG genotype often experience digestive problems with milk sugar—this is known as lactose intolerance.
Test details:
The test examines two variants, c.-13910T/C (rs4988235) and c.-22018A/G (rs182549), in the regulatory region of the LCT gene, which codes for the lactase enzyme that is essential for digesting milk sugar (lactose). Adults with the CC/GG genotype often experience digestive problems with milk sugar—this is known as lactose intolerance.
The examination is performed using the Real-Time PCR method, which detects both mentioned polymorphisms/mutations in the LCT gene using a pair of fluorescently-labeled probes (allelic discrimination). The methods used have a 99.9% sensitivity and specificity.
