Partial Androgen Insensitivity Syndrome Presenting with Gynecomastia

Area of Science:

• Endocrinology
• Genetics
• Male Reproductive Health

Background:

• Gynecomastia is the benign enlargement of male breast glandular tissue.
• Identifying causes, including endocrine disorders, is crucial for diagnosis and management.
• Androgen Insensitivity Syndrome (AIS) is a rare genetic condition affecting male sexual differentiation, characterized by mutations in the androgen receptor gene.

Purpose of the Study:

• To investigate the link between Androgen Insensitivity Syndrome (AIS) and gynecomastia.
• To report a case of partial AIS presenting with gynecomastia.
• To identify the specific androgen receptor gene mutation in the presented case.

Main Methods:

• Clinical case presentation.
• Genetic analysis to identify androgen receptor gene mutations.
• Phenotypic classification of Androgen Insensitivity Syndrome (AIS).

Main Results:

• A case of partial AIS was identified presenting with gynecomastia.
• A specific mutation in the androgen receptor gene was identified in this patient.
• The patient exhibited characteristics consistent with partial AIS.

Conclusions:

• Gynecomastia can be a presenting symptom of partial Androgen Insensitivity Syndrome (AIS).
• Genetic analysis of the androgen receptor gene is essential for diagnosing AIS.
• Understanding the genetic basis of AIS is vital for managing associated conditions like gynecomastia.
