Beyond Binary: Gender Reassignment in a Case of 11β-Hydroxylase Deficiency

Area of Science:

• Endocrinology
• Genetics
• Pediatric Medicine

Background:

• Congenital adrenal hyperplasia (CAH) comprises inherited disorders of adrenal hormone biosynthesis, primarily affecting cortisol production.
• These conditions are characterized by enzyme deficiencies, leading to variable clinical presentations based on the specific enzyme and severity.
• Autosomal recessive inheritance is typical for most CAH forms.

Observation:

• A patient presented with early-onset hypertension, hematuria, precocious puberty, and gynecomastia.
• Genetic analysis revealed an XX karyotype, inconsistent with the initial male presentation.
• Pelvic ultrasound confirmed female internal reproductive organs (uterus, ovaries, vagina).

Findings:

• The case details 11β-hydroxylase deficiency (11βOHD), a specific form of CAH.
• The patient exhibited a rare presentation of 11βOHD in an XX individual with apparent male external characteristics.
• Gender reassignment surgery was performed due to the complex presentation.

Implications:

• This case underscores the critical importance of recognizing and managing CAH promptly.
• Accurate diagnosis and timely intervention are essential for the well-being of individuals with CAH.
• The variability in CAH presentation necessitates a comprehensive diagnostic approach.
