Dataset Summary

Title	Extracellular Glutathione Peroxidase 3 GPx3 Levels are Markedly Reduced in Children Affected with Konzo an Irreversible Spastic Paralysis Associated with Food Poisoning
Description	Konzo, a neglected paralytic neurological disease associated with food (cassava) poisoning, affects the world poorest children and women of childbearing ages across regions of sub Saharan Africa, with the Democratic Republic of the Congo having the largest case burden. The primary risk factors for development include a dietary reliance on cyanogenic rich cassava and malnutrition, factors which are exacerbated by environmental stressors such as drought and famine. Despite understanding the dietary risks that lead to konzo, the molecular markers and mechanisms that trigger this disease remain unknown. Plasma, collected from two large independent cohorts 10 years apart, were subjected to multiple high throughput mass spectrometry in search of disease biomarkers and proteins that were differentially expressed in children affected with konzo relative to those unaffected, including their siblings. DDA experiment was performed on the first cohort with a validation by SRM analysis. For the second cohort, DIA experiment was performed with a validation by PRM.
