ABSTRACT
<p><b>OBJECTIVE</b>To analyze the mutation of the keratin 9 gene (KRT9) in a pedigree with epidermolytic plamoplantar keratoderma (EPPK).</p><p><b>METHODS</b>Blood samples were obtained from 4 affected and 3 normal individuals in this family. Mutation screening was carried out by polymerase chain reaction (PCR) and direct DNA sequencing.</p><p><b>RESULTS</b>A heterozygous nucleotide C to T transition at position 484 in exon 1 of the KRT9 gene was detected in the 3 affected in this family, but was not found in normal individuals in the family and 100 unrelated individuals.</p><p><b>CONCLUSION</b>A missense mutation (484 C to T) in the KRT9 gene has been detected in this EPPK family, which is probably one of the molecular bases of the pathogenesis of the disease.</p>
