AR Genotyping

Meaning

AR Genotyping is the clinical and molecular process of analyzing an individual’s Androgen Receptor gene to identify specific polymorphisms, such as the length of the CAG trinucleotide repeat sequence. This genetic analysis provides crucial insight into the functional sensitivity of the androgen receptor to circulating androgens like testosterone and dihydrotestosterone. Understanding these genetic variations allows clinicians to predict potential differences in tissue response to hormone signaling, which is essential for personalized hormonal health strategies. The androgen receptor plays a pivotal role in regulating gene expression across numerous physiological systems, influencing muscle mass, bone density, mood, and sexual function.
