Neurofilaments usually contain three intermediate filament proteins: NEFL, NEFM, and NEFH which are involved in the maintenance of neuronal caliber. NEFH has an important function in mature axons that is not subserved by the two smaller NF proteins. May additionally cooperate with the neuronal intermediate filament proteins PRPH and INA to form neuronal filamentous networks.

Findings in the dorsolateral prefrontal cortex in schizophrenia provide evidence of altered proteins involved in synaptic function (FABP4), cytoarchitecture organization (NEFH), and circadian molecular clock signaling (CSNK1E), which may be contributing to the cognitive and/or negative symptoms in this disorder. FABP4, CSNK1E and NEFH could become potentially useful biomarkers for schizophrenia. PMID: 27236410
Unique deletions of two nucleotides causing frameshifts near the end of the NEFH coding sequence were identified in two Charcot-Marie-Tooth disease families.

Study found a significant correlation between values of 8-hydroxy-2'-deoxyguanosine and phosphorylated NF-H only in clinically isolated syndrome group. While the plasma values of 8-hydroxy-2'-deoxyguanosine reflect the degree of acute demyelination in clinically isolated syndrome, phosphorylated NF-H values reflect that in relapsing-remitting multiple sclerosis.
