Abstract

Background Luteinizing hormone (LH) is a useful parameter in diagnosing precocious puberty. The pubertal response of serum LH to a GnRH stimulation test is varied, and clinical symptoms of precocious puberty are sometimes disproportionate with serum LH concentrations. Many patients present in a state of precocious puberty that advances rapidly, but the post-GnRH peak LH remains prepubertal. LH receptor mutations are suspected of involvement in the non-classic type of central precocious puberty (CPP).

Objective To examine the association between LHCGR polymorphism and non-classic CPP in subjects exhibiting a peak LH<5 IU/L on a GnRH stimulation test. Methods: In total, 102 girls with non-classic CPP and 100 normal adult women were enrolled. All subjects underwent LHCGR gene analysis by the Sanger method, and patients and controls were compared. Auxological data and gonadotropin concentrations were analyzed in the 102 patients. Of these patients, 75 completed GnRH agonist treatment, and the treatment outcomes were analyzed.

Results A total of seven variants were identified, including two missense mutations (g.48698754 G/A and g.48688613 G/A) that were found in the patient group (no patients contained both mutations). In silico analysis of these missense mutations suggested the possibility of damaging the LHCGR. However, no significant association was found between the identified LHCGR variants and non-classic CPP. GnRH agonist treatment decreased bone age advancement and increased predicted adult height.

Conclusions LHCGR gene polymorphisms do not appear to be a major causative factor for the relatively low concentration of LH in patients with non-classic CPP. GnRH agonist treatment improved clinical parameters in these patients.
