A total of 38 cases have been reported in the literature since the disease was initially described in 1985, but only 14 mutations in <jats:italic>COL7A1<\/jats:italic>, the gene responsible for the disease, have been detected in families with BDN.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>We report a Chinese male infant with BDN and indirect inguinal hernia, in whom a novel <jats:italic>de novo<\/jats:italic> mutation in <jats:italic>COL7A1<\/jats:italic> was demonstrated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>DNA was obtained from the blood of the patient and his parents.
