Hypothalamic growth hormone deficiency in a patient with ring chromosome 18.
We report on a boy with a ring 18 chromosome associated with hypothalamic growth hormone (GH) deficiency. A 12-month trial of GH replacement therapy (0.5 U/kg/week) resulted in a marked growth acceleration. Our findings emphasise the need of evaluating GH secretion in patients with abnormalities of the 18 chromosome.
