Besides, higher levels of serum neurofilament light chain (sNfL), a marker of axonal damage in different neurological conditions, were associated with lower cognitive performance in patients with CIDP, while a link between sNfL and the sensorimotor impairment was no found [19], so that sNfL in CIDP may, at least partially, reflect central axonal impairment. The gene discussed is NEFL; the disease is chronic inflammatory demyelinating polyradiculoneuropathy.
