A patchy distribution is observed with accentuation on the thenars, hypothenars and the arches of the feet. The disease becomes apparent in infancy and is associated with sensorineural hearing loss that shows a variable age of onset. Due to genetic and clinical similarities, it has been proposed that palmoplantar keratoderma-deafness syndrome, knuckle pads-leukonychia-sensorineural deafness-palmoplantar hyperkeratosis syndrome and keratoderma hereditarium mutilans may represent variants of one broad disorder of syndromic deafness with heterogeneous phenotype. The disease is transmitted in an autosomal dominant manner with incomplete penetrance. palmoplantar keratoderma-hearing loss syndrome MONDO:0007852 GARD:0003094 diffuse palmoplantar keratoderma with deafness (subtype) palmoplantar hyperkeratosis-deafness syndrome palmoplantar keratoderma and sensorineural deafness UMLS:C1835672 MEDGEN:332030 palmoplantar hyperkeratosis-hearing loss syndrome keratoderma palmoplantar deafness MESH:C536152 DOID:0111505 diffuse palmoplantar keratoderma
