Contrarily, lower anti-PGL-1 serology levels, characterizing the paucibacillary form, were observed in the multiple mononeuropathy patient group, suggesting a stronger cellular response and corroborating the greater immune aggression of nerves, which is evidenced by the greater severity of the peripheral neuropathy, with greater number of altered nerves, higher proportion of sensory-motor symptoms, and thickened nerves. The gene discussed is SDHD; the disease is peripheral neuropathy.
