Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.
