Background: The androgen receptor (AR) is essential for the development of primary and secondary male characteristics and is activated by its ligand dihydrotestosterone (DHT). Reduced AR activity can cause undervirilization and infertility. We recently developed an assay to test AR function as a ligand-dependent transcriptional activator in human genital skin fibroblasts (GF). So far it is unclear, if AR expression levels correlate with AR function in the male external genital...

Background: In a large fraction of patients with clinically presumed Androgen Insensitivity Syndrome, no mutation of the Androgen Receptor gene can be detected. However, established Sanger sequencing techniques of the AR gene are often limited to the coding region.Objective and Hypotheses: To set up a next generation sequencing (NGS) approach of the entire AR locus (including UTRs, exons, introns, up- and downstream regions) for a comprehensive ...
