Detection of the most common nonfunctional DPD alleles by loop-mediated isothermal amplification.
The LAMP Human DPD deficiency KIT (LC-DPD4mut-LP) is an in vitro diagnostic test intended for the qualitative detection of four different non-functional or less functional DPYD alleles. This assay is dedicated to professional use in diagnostic laboratory. The device is not for self-testing.
DPD deficiency is an autosomal recessive metabolic disorder due to a decreased activity of the enzyme dihydropyrimidine dehydrogenase (DPD), an enzyme that catalyses the rate-limiting step in 5-FU metabolism, encoded by the DPYD gene. Individuals who carry at least one copy of no-function DPYD variants, may not be able to metabolize those drugs at normal rates, and are at risk of potentially life-threatening toxicity. The stratification of patients based on the DPYD genotype may help to prevent such adverse events. The prevalence of DPD deficiency in Caucasians is approximately 3%-5%. Symptomatic DPD deficiency is typically caused by homozygous inactivation of DPYD; whereas individuals who are heterozygotes tend to be asymptomatic. Signs of fluoropyrimidine toxicity include severe diarrhea, severe mucositis, neutropenia, neurotoxicity, and handfoot syndrome (redness, swelling, and blisters on the palms of the hands and soles of the feet).
