Mutation detection of the human glucocorticoid receptor alpha gene area coding for the hormone-binding domain by denaturing gradient gel electrophoresis.

Mutations in the hormone-binding domain of the human glucocorticoid receptor alpha (hGRalpha) gene have been detected in a variety of glucocorticoid resistance syndromes. Using the denaturing gradient gel electrophoresis technique, we developed a sensitive method for the detection of alterations in the gene area coding for the whole hormone-binding domain and part of the DNA-binding domain of the hGRalpha. This method can be applied for screening of glucocorticoid receptor gene alterations in glucocorticoid-dependent diseases.
