Figure 6. PvuII digestion of PCR products for the c.892C>T transition. PCR products in individuals with the c.892C>T transition were digested into 153 bp and 173 bp and into only 153 bp in individuals without the c.892C>T transition. A: Members of the Chinese family with MCD. PCR products from individuals II:2, III:1, III:2, III:4, III:6 and IV:1 with c.892C>T transition were digested into 153bp and 173bp, other members without c.892C>T transition only had a 153bp segment. B :Part of 100 control subjects. Control subjects without c.892C>T transition only had a 153bp segment. M indicates DNA ladder, U indicates undigested PCR product, and P indicates one patient with MCD in the Chinese family.
