Abstract：
OBJECTIVES:A conformation sensitive gel electrophoresis (CSGE) method was modified for detection of LDL receptor gene mutations. DESIGN AND METHODS:Usage of a temperature gradient against running time was tested with 33 identified mutations in the LDL receptor gene. Most of the mutations were missense. RESULTS:32 mutations were detected using this method (sensitivity: 97%). The duration required for running the test for each of the exons was reduced to 3-4 h. CONCLUSIONS:This modified CSGE method may be used as a screening procedure in genetic diseases where a variety of mutations may cause illness.
