Candidate gene approach of familial morbid obesity: linkage analysis of the glucocorticoid receptor gene.

Abstract

The GRL locus does not appear to be a major locus for obesity, but we cannot exclude that this gene or gene located nearby may have some minor effects on the obese phenotype or may be involved in some subtypes of obesity. Larger cohorts of families are probably necessary to improve the power of such linkage analysis in this heterogeneous disease.
