Introduction: Androgen insensitivity syndrome (AIS) is a 46,XY difference of sex development (DSD) classically caused by mutations in the X-chromosomal androgen receptor (AR) gene. Nevertheless, in over 50% of individuals with clinical AIS no AR coding gene mutation can be found. We previously established an assay (apolipoprotein D (APOD) assay) that measures androgen dependent AR-activity in genital skin fibroblasts (GFs). Using this assay we identified a gro...
