The 麻豆传媒高清版 (WCM) Klinefelter Syndrome Care Center offers multidisciplinary care for children and adults with Klinefelter syndrome. This program brings together a broad team of experts to offer our patients comprehensive evaluation and subspecialty care. Our goal is to provide the best care based on advances in health information and evidence-based treatment. We are part of the Association for X and Y Chromosome Variations (AXYS) and the AXYS Clinic Consortium with ongoing efforts to improve clinical care, education, and research.

What is Klinefelter Syndrome?

Klinefelter syndrome is a genetic condition that occurs when a boy is born with an extra copy of the X chromosome. 47, XXY is the most common of the X and Y variants and approximately, 1 in 500 males have an extra copy of the X chromosome. We see families at all ages for genetic counseling and coordination of care. With advances in prenatal screening, families may be referred for genetic counseling and get clarification about a new diagnosis. 

Children and adults with 47, XXY may present with subtle or varying symptoms without obvious physical differences. There may be growth or developmental concerns in early childhood for which referrals are needed in endocrinology, developmental-behavioral pediatrics or speech-language therapy. 

From adolescence to young adulthood, our endocrinologists and urologists can individualize care and treatment to meet specific needs, such as testosterone replacement and fertility management. Adults may often not be detected with 47, XXY until an infertility evaluation, while others who have known about their diagnosis for years may now need fertility-related care or genetic counseling for reproductive planning.
