E34.52

Clinical Causes: Mutations in the androgen receptor (AR) gene, which impair the body's ability to respond to male hormones Inheritance as an X-linked trait, meaning the gene mutation is on the X chromosome Genetic variations that reduce androgen receptor functionality, leading to partial insensitivity

Key Symptoms: Ambiguous genitalia or atypical development of the genital organs in XY individuals Variable size and shape of the testes Presence of gynecomastia (enlarged breast tissue) in some cases Undescended or partially descended testes Normal or partially developed internal reproductive structures such as the prostate Potential fertility issues due to incomplete development of reproductive organs Normal or slightly altered secondary sexual characteristics depending on the severity of insensitivity

Diagnosis Path: Diagnosing partial androgen insensitivity syndrome involves a combination of clinical evaluation, hormonal testing, and genetic analysis. Healthcare providers may assess physical features and perform blood tests to measure hormone levels, including testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Genetic testing can identify mutations in the androgen receptor gene, confirming the diagnosis. Imaging studies, such as ultrasound, may be utilized to evaluate reproductive organs and testicular position.

Treatment Protocols: Management of PAIS is individualized based on the specific features and needs of each person. Approaches may include hormone therapy to develop or enhance secondary sexual characteristics, surgical procedures to correct genital anomalies, and fertility counseling. Psychological support and counseling are often recommended to help individuals cope with the physical and emotional aspects of the condition. Multidisciplinary care involving endocrinologists, urologists, geneticists, and mental health professionals is essential for optimal outcomes.
