Case Description:

The phenotype of the deficiency of heterozygote 11 beta-hydroxylase composed of the Q356X and R384X mutations is described.

Clinical Findings:

Severe virilization, peripheral hypertension, and early puberty.

Treatment and Outcome:

Managed with hormone replacement therapy (corticosteroid) and antihypertensive therapy (beta-blocker), resulting in the control of physical changes and levels of arterial tension.

Clinical Relevance:

According to the phenotypic characteristics of the patient, it is inferred that theR384X mutation carries an additional burden on the Q356X mutation, with the latter previously described as a cause of 11 beta-hydroxylase deficiency. The description of a new genotype, as in this case, expands the understanding of the hereditary burden and deciphers the various factors that lead to this pathology as well as the other forms of congenital adrenal hyperplasia (CAH), presenting with a broad spectrum of clinical presentations. This study highlights the importance of a complete description of the patient's CAH genetic profile as well as their parents' genetic profile.
