ZFHX2 is a transcriptional regulator critical for pain perception and noxious stimulus processing. As a zinc finger homeobox protein containing three homeobox domains and 18 zinc-finger motifs, ZFHX2 functions as a DNA-binding transcription factor expressed in small diameter sensory neurons and differentiating neurons in the brain 1. ZFHX2 regulates genes implicated in peripheral pain mechanisms, with both null mutations and point mutations (p.R1913K) causing significant pain insensitivity characterized by hyposensitivity to noxious heat and painless bone fractures 1. In the brain, ZFHX2 influences emotional processing through monoaminergic neurons; Zfhx2-deficient mice display hyperactivity, enhanced depression-like behaviors, and altered anxiety phenotypes 2. Mutations in ZFHX2 cause Marsili syndrome, an autosomal dominant disorder characterized by recurrent fever, anhidrosis, pain insensitivity, and diminished corneal reflexes—clinically distinct from congenital insensitivity to pain with anhidrosis (CIPA) 3. ZFHX2-AS1, a long non-coding RNA antisense to ZFHX2, functions as a tumor suppressor in ovarian cancer and shows altered expression in various pathological conditions including hepatitis B and cirrhosis 4, 5, 6. These findings identify ZFHX2 as a human-validated analgesic drug target with potential therapeutic applications for chr14 pain management.
