The amino acid N14 is near two of the residues mutated in Keratitis-like ichthyosis deafness (KID) syndrome (p.G12R and p.S17F), yet the phenotype associated with p.N14K strongly differs from the KID phenotype, having a phenotype more similar to Clouston syndrome (caused by mutations in GJB6). This evidence concerns the gene GJB6 and KID syndrome.
