Abstract

We report on a pair of male monozygotic twins, one unaffected and the other affected with gonadotropin-releasing hormone (GnRH)-dependent precocious puberty, and discuss the role of treatment with a GnRH analog in the attainment of full height potential in GnRH-dependent precocious puberty. At 1.6 years of age, the affected twin was studied for tall stature (+3.8 SD), and was diagnosed as having GnRH-dependent precocious puberty due to a hypothalamic hamartoma of the tuber cinereum. He was treated with oral cyproterone acetate (110-170 mg/m2 daily) from 1.8 through 5.0 years of age, with oral cyproterone acetate and intranasal buserelin acetate (700-900 μg/m2 daily) from 5.0 through 7.5 years, and with intranasal buserelin acetate alone (1100-1400 μg/m2 daily) from 7.5 through 12.6 years. He attained a final height of 171.0 cm at 14.9 years of age (+0.10 SD) and his twin 170.0 cm at 15.3 years of age (-0.10 SD), with their target height being 174.5 ± 9.0 cm. Conclusion: This study indicates that GnRH analog treatment may preserve near full height potential in some patients with GnRH-dependent precocious puberty.
