Detection method: allelic discrimination

The kit is intended for detection of mutation A149P, A174D, N334K and deletion del4E4 in the ALDOB gene in human genomic DNA. Detection is based on real-time polymerase chain reaction (qPCR) using fluorescently labelled probes (allelic discrimination).

Clinical implications

Hereditary fructose intolerance (HFI) is an autosomal recessive disorder caused by a deficiency of the enzyme aldolase B, which is essential for the metabolism of fructose. One person in 10,000 to 100,000 suffers from HFI. The most common mutations of the gene for aldolase B are A149P, A174D, N334K and deletion of del4E4.

Hereditary fructose intolerance is characterized by clinical symptoms such as vomiting, nausea, diarrhea, growth restriction and metabolic disorders (hypoglykemia, hyperuricemia, hypomagnesemia, or lactic acidosis). HFI may also lead to liver and kidney failure. HFI first appears in infants who are not breastfed, but eat a diet containing sucrose and fructose.

gb Easy PCR Master Mix consists of hot-start Taq DNA polymerase, reaction buffer, dNTP and MgCl2. Taq polymerase is chemically modified DNA polymerase from Thermus aquaticus. This polymerase is completely inactive at room temperature but it is rapidly activated during the initial denaturation step of PCR.
