GJB2: gap junction protein b2 KID: keratitis-ichthyosis-deafness INTRODUCTION Keratitis-ichthyosis-deafness (KID) syndrome is a rare genodermatosis with approximately 100 published cases. Although it is classified as an autosomal dominant disorder, more than 90% of cases are caused by sporadic mutations predominantly in gap junction protein b2 (GJB2) on chromosome 13q11-q12 (OMIM 148210). GJB2 encodes connexin 26, a gap junction protein, which plays a role in epithelial differentiation. The characteristic clinical triad includes bilateral sensorineural hearing loss, vascularizing keratitis, and erythrokeratoderma. Treatment with acitretin is reported to clear hyperkeratotic ichthyotic lesions with little effect on vision and hearing.

Connexin 26 (GJB2) mutations in two Swedish patients with atypical Vohwinkel (mutilating keratoderma plus deafness) and KID syndrome both extensively treated with acitretin.
Neuroectodermal syndromes involving the skin and inner ear may be associated with mutations in connexin proteins, which form gap junctions important for intercellular communication. Vohwinkel syndrome (keratodermia mutilans with hearing loss) and keratitis-ichthyosis-deafness (KID) syndrome are rare ectodermal dysplasias associated with dominant mutations in the GJB2 gene encoding connexin 26. ...

INTRODUCTION Keratitis-ichthyosis-deafness (KID) syndrome is a rare congenital multisystem disorder affecting certain tissues of ectodermal origin such as epidermis, cochlea, and cornea, leading mainly to palmoplantar hyperkeratosis, ichthyosiform scaling, deafness, and blindness. The author reports for the first time in the Middle East three family members suffering from KID syndrome in the so...
متن کاملCochlear Implantation in Patients with Keratitis-Ichthyosis-Deafness Syndrome: A Report of Two Cases
Background Keratitis-ichthyosis-deafness (KID) syndrome is a syndrome which presents with hearing loss and visual and keratinization disorders. In such patients, hearing aids cannot be effectively used in the rehabilitation of hearing loss because of the frequent blockage of the external ear canal with epithelial debris and due to dry and tense skin of the external ear canal. Moreover, severe o...
متن کاملMultiple Scalp Lesions in a Patient with Keratitis, Ichthyosis and Deafness Syndrome Mimicking Metastatic Squamous Cell Carcinoma on 18F-FDG PET/CT
We report the case of a 17-year-old girl with keratitis, ichthyosis, and deafness (KID) syndrome. As a complication of her KID syndrome she developed squamous cell carcinoma at the left index finger. Additional clinical features were multiple soft tissue lesions over the scalp mimicking metastatic disease on 18F-FDG PET/CT. To our knowledge, this is the first case report about the uptake patter...
