A family with five members who have variable findings of leuconychia, knuckle pads, hearing loss, and palmoplantar hyperkeratosis is described. The findings in these subjects are compared with those noted in previously reported patients with Bart-Pumphrey syndrome. The range of disorders which include knuckle pads as part of the phenotype is reviewed.

All member of family referred to our clinic complaining of white nails. Physical examination revealed clinical features of leukonychia totalis and also the presence of sensor ineural hearing loss (SNHL), palmoplantar keratoderma (PPK) and knuckle pads, the four essential criteria for the diagnosis of Bart Pumphrey syndrome. Three generations were affected with variable presentations in ma...

We report on a 22-year-old male patient and his father, both presenting with congenital sensorineural deafness, diffuse palmoplantar keratoderma and knuckle pads. These findings are similar to those previously described in the Bart-Pumphrey syndrome, a rare autosomal dominant disorder. Several conditions including keratoderma and deafness are briefly reviewed.

Knuckle pads are a rare, frequently overlooked, thickening of the skin usually overlying the extensor surface of the proximal interphalangeal joints. They are well- circumscribed, benign lesions that generally do not require treatment. Idiopathic knuckle pads must be differentiated from similar appearing lesions or trauma-induced pseudo-knuckle pads. Knuckle pads have been observed in associati...

Connexin 30 (Cx30), a member of the large gap-junction protein family, plays a role in the homeostasis of the epidermis and inner ear through gap junctional intercellular communication (GJIC). Here, we investigate the underlying mechanisms of four autosomal dominant Cx30 gene mutations that are linked to hearing loss and/or various skin diseases. First, the T5M mutant linked to non-syndromic he...
