ABSTRACT
Objective:
To report the diagnosis, treatment, and follow-up of a 21-hydroxylase deficiency boy with central precocious puberty caused by complex heterozygous mutation of CYP21A2 gene.Methods:
The child was symptomatic of rapid growth and secondary sexual characteristics at the age of 6. The diagnosis of central precocious puberty was confirmed by serum testosterone, gonadotropin levels, and gonadotropin-releasing hormone (GnRH) stimulation test. 21-hydroxylase deficiency was diagnosed clinically based on the serum adrenocorticotropic hormone (ACTH), 17-hydroxyprogesterone levels, and images on the computed comography (CT) of the adrenal glands.Results:
The CYP21A2 gene was detected to have a compound heterozygous mutation by Sanger sequencing and multiplex ligation-dependent probe amplification. During the 3 years follow-up, the effects of glucocorticoids, GnRH analogs, and recombinant human growth hormone were regularly monitored and evaluated.Conclusions:
Glucocorticoid replacement followed the principle of the lowest effective dose. GnRH analogs showed an effective inhibition of the hypothalamus-pituitary-gonadal axis, while recombinant human growth hormone had no such growth-promoting effect.
