Bart-Pumphrey Syndrome, also known as knuckle pads, leukonychia, and sensorineural deafness, is related to keratoderma, palmoplantar, with deafness and palmoplantar keratosis. An important gene associated with Bart-Pumphrey Syndrome is GJB2 (Gap Junction Protein Beta 2), and among its related pathways/superpathways are Vesicle-mediated transport and G-protein signaling G-Protein alpha-i signaling cascades. Affiliated tissues include skin and pancreas, and related phenotypes are congenital sensorineural hearing impairment and leukonychia
