ZNF334 truncation mutation drives cold-induced autoinflammation

ABSTRACT: The role of zinc finger protein 334 (ZNF334) in immunological processes remains unknown. We identified a ZNF334 truncation mutation (p.Thr399fs) in a rare case of late-onset cold-induced autoinflammatory disease with elevated TNF-α, IL-1β, IL-6, and extracellular heat shock protein 90 (eHsp90) plasma levels and progressive sensorineural hearing loss. Using patient-derived monocytes and CRISPR/Cas9-edited THP-1 monocytes with a ZNF334 truncation mutation, we discovered that the mutation reduced the interaction between ZNF334 and Hsp90, diminished the endogenous levels of the cold stress regulators Hsp90 and transient receptor potential melastatin 8 (TRPM8), disrupted ER protein folding response and redox homeostasis, and increased cold-induced NF-κB activation and secretion of the proinflam
