In 2015, the AXYS Board of Directors voted to approve funds to help develop the AXYS Clinic and Research Consortium (ACRC). This exciting development committed us to help organize, fund and build out a clinic consortium that will operate as independent clinics committed to collaborating with one another, sharing informational resources, and exploring opportunities to participate in joint research projects. In addition, AXYS organizes annual meetings of the consortium at which members meet to discuss topics important to the X and Y variation community.

The goal of AXYS is to ensure that all families impacted by any of the chromosome variations have access to the best available evaluation, treatment or treatment recommendations. The AXYS Clinic & Research Consortium is an important means of achieving that goal.

For help in determining which clinic might be most appropriate for you or your family, please read the following and/or call us at 1-888-999-9428.

Types of Clinics

Due to the many X and Y chromosome variations, not all clinics offer services for all conditions. Below is a listing of ACRC clinics. The specific conditions and patient ages served by the clinic are noted in the description.

Multidisciplinary Clinics

Some clinics are multidisciplinary in their services. A multidisciplinary clinic provides a comprehensive, integrated approach to caring for individuals. Patient visits are organized to provide access to all necessary medical, psychological, and therapy disciplines in one visit. Professionals then meet, discuss each case, then collaborate to develop a fully coordinated care plan tailored to the patient. Some clinics also provide “take-home” materials for local medical, therapy and school professionals. Please review each clinic’s website and/or description of its services for information regarding its specific approach to seeing patients. If you’re unsure about the types of services provided, be sure to ask at the time you schedule your appointment.

Research and Clinical Trials


Toward Better Diagnosis and Treatments

Research is the lifeblood of all medical conditions that stand to be improved as we learn more about them. No serious advance can be made against diseases without carefully constructed scientific research. Research helps raise awareness, inspire hope, and lead to early diagnosis and effective treatments.

Many studies on X and Y variations take place simultaneously at research centers around the world. If you want to know more about individual studies, scroll down the page and click on the website or email links directing you, or simply follow the instructions listed for each study.

If you are new to these conditions and the nature of clinical trials, click here for more information.

Post New Trials

If you are the Principal Investigator or other responsible person for a study that you believe may be applicable to one or more of the X and Y variations that AXYS serves, we would be happy to post information concerning your research on our website.

Prior Conferences

Every two years, AXYS sponsors a conference that brings together those with an extra X or Y chromosome variation, their parents or other family members, researchers, medical professionals and others. The conference features individual presentations, panel discussions, and plentiful opportunity for informal discussion and support on a wide range of matters relevant to our members and friends. Much of the material is of a timeless nature that can be highly informative and helpful to those new to the field.
