Overview
Androgen insensitivity syndrome is caused due to mutations in the X-linked androgen receptor gene.
Causes
- Androgen insensitivity syndrome is caused due to mutations in the X-linked androgen receptor gene, which encodes for the ligand-activated androgen receptor—a transcription factor.
- Defects in the AR gene prevent the normal development of both internal and external genital structures in 46,XY individuals, causing a variety of phenotypes ranging from male infertility to completely normal female external genitalia. [1]
- More than 800 mutations in the AR gene have been reported in AIS patients. [2]
- AIS phenotype majorly depends on the degree of residual androgen receptor (AR) activity
- Most severe mutations are generally associated with a CAIS phenotype.
