#ExistInterpData>Background Information for Glucose-6-Phosphate Dehydrogenase (G6PD) 2 Mutations: Characteristics: Neonatal jaundice, episodes of acute hemolytic anemia in response to oxidative stress such as infection, medication, and fava beans. Drug Sensitivities: Adriamycine and other anthracycline chemotherapy agents, Dapsone, Flutamide, Mafenide cream, Methylene blue, Nalidixic acid, Nitrofurantoin, Phenazopyridine, Primaquine, Rasburicase, Sulfacetamide, Sulfamethoxazole, and Sulfanilamide. Incidence: 1 in 10 males of African descent; less common in other ethnicities. Inheritance: X-linked recessive. Cause: Deleterious mutations in only the Glucose-6-Phosphate Dehydrogenase (G6PD) gene. Mutations Tested: A376G and G202A (A- allele: both mutations present in cis; A+ allele: A376G alone; G202A is rarely if ever seen alone). Clinical Sensitivity: 99 percent in individuals of African descent. Methodology: Allele-specific hydrolysis probes (TaqMan®) and fluorescent monitoring. Analytical Sensitivity and Specificity: 99 percent. Limitations: Only the two G6PD gene mutations targeted (A376G and G202A) will be detected; analytical sensitivity may be affected by rare primer or probe site mutations.
