Figure 4. Analysis of R124C mutation by polymerase chain reaction-restriction fragment length polymorphism. All affected individuals carry the same mutation in exon 4 of the TGFBI gene. Exon 4 was amplified from each family member and digested with PstI. The products were analyzed by a 4% agarose gel electrophoresis along with a standard marker (MW) as indicated.
