Complete androgen insensitivity syndrome: diagnosis and management

Area of Science:

• Genetics
• Endocrinology
• Reproductive Medicine

Background:

• Complete androgen insensitivity syndrome (CAIS) is an X-linked genetic disorder in 46,XY individuals.
• It results from loss-of-function mutations in the androgen receptor gene, causing complete peripheral androgen resistance.
• Patients present with a female phenotype, undescended testes, absence of a uterus, and typically a short vagina.

Purpose of the Study:

• To emphasize accurate diagnosis of CAIS compared to partial androgen insensitivity syndrome (PAIS) and other disorders of sex development (DSD).
• To discuss optimal management strategies for CAIS patients in the context of current consensus statements.
• To provide insights into screening, gonad and vaginal surgery, and ethical considerations in CAIS management.

Main Methods:

• Review of current literature and clinical guidelines on CAIS.
• Focus on diagnostic methods, including androgen receptor genotyping.
• Discussion of surgical and ethical considerations in patient management.

Main Results:

• Accurate diagnosis through androgen receptor genotyping is vital for differentiating CAIS from PAIS and other DSDs.
• Optimal management involves careful consideration of gonadectomy versus conservative approaches, balancing hormonal function against malignancy risk.
• Vaginal adequacy and ethical disclosure are key components of patient care.

Conclusions:

• Precise diagnosis of CAIS is essential for appropriate patient management.
• A multidisciplinary approach is necessary for optimizing surgical and ethical care, including gonad and vaginal management.
• Adherence to consensus guidelines ensures comprehensive and ethical treatment for individuals with CAIS.
