Based on the IgG seropositivity, Figure  shows that the tested peptides, PEP1, PEP2, PEP3, PEP4, and PEP5, were effective in distinguishing healthy individuals (NegativeControl) from leprosy patients, as well as household contacts of paucibacillary(HHC-PB) and multibacillary (HHC-MB) leprosy patients, with significantdifferences observed across all groups. Here, VPS18 is linked to leprosy.
