A modified conformation sensitive gel electrophoresis (CSGE) method for rapid and accurate detection of low density lipoprotein (LDL) receptor gene mutations in Familial Hypercholesterolemia.

摘要

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.
