Abstract
Epidermolytic plamoplantar keratoderma (EPPK) is an autosomal dominant inherited disease. It caused by mutations in the highly conserved coil 1A domain of the keratin 9 gene, KRT9. We studied a four-generation family with EPPK combined with knuckle pads from Jiangsu province, China. In this study, a heterozygous nucleotide T-->C transition at position 500 in exon 1 of KRT9 was detected, which resulted in a leucine to serine (L167S) change. We describe this mutation in a Chinese pedigree with EPPK with knuckle pads for the first time, demonstrating the prevalence of this mutation in diverse population.
