Mutations in GJB2 (connexin26) are associated with skin disorders and deafness. The Clouston syndrome (MIM129500) is associated with mutations in GJB6 (connexin30). Here, we describe a patient suffering from a Clouston-syndrome-like phenotype of thin hair, deafness, nail dystrophy, and mild erythrokeratoderma, caused by a novel spontaneous missense mutation in GJB2. The heterozygous mutation in codon 42, AAC>AAG, changes asparagine to lysine (N14K). Interestingly, this asparagine is near two of the residues mutated in Keratitis-like ichthyosis deafness (KID) syndrome (G12R and S17F), yet the phenotype associated with N14K strongly differs from the KID phenotype. Instead, there is a clear phenotypic overlap with syndromes associated with connexin26 or 30 mutations. Our finding suggest that careful audiological evaluation of patients suffering from Clouston-syndrome-like phenotypes is warranted and expand the spectrum of connexin26-associated disease.
