Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

XXY/Klinefelter Syndrome in 2000: Expanding the Phenotype and Identifying New Research Directions
Thursday, August 31, 2000 -
Wednesday, August 30, 2000
Location: NIH Campus, Bethesda, MD
Description: The clinical and research objectives of this conference were to summarize current knowledge concerning the incidence of Klinefelter syndrome and its genetic (cytologic) basis, clarifying the role X-inactivation plays in the widely varied phenotype; summarize the spectrum of clinical features in XXY Klinefelter syndrome—reproductive dysfunction, structural anomalies, and neurologic/cognitive/behavioral dysfunction; review current treatment and management of hormonal deficiency, infertility, and neurologic/behavioral perturbation; summarize current beliefs concerning the biologic basis of functional defects; and delineate those new research areas that would benefit from more focused attention.
