We found that IL-17-CIDP patients were significantly younger (Fig 4C), had a trend towards shorter self-reported disease duration (Fig 4D) and higher tibial nerve CMAP amplitudes (Fig 4E) than non-IL-17-CIDP patients, while histological parameters did not differ (S3 Table). The gene discussed is IL17A; the disease is chronic inflammatory demyelinating polyradiculoneuropathy.
