What Is the American Association for Klinefelter Syndrome (AAKSIS) and How Can You Contact It?

The American Association for Klinefelter Syndrome Information and Support (AAKSIS) is a national volunteer association focused on education, support, research, and understanding of 47,XXY and its variants, collectively known as Klinefelter syndrome. If you are an individual with XXY, a family member, or a clinician looking for a patient-support organization, AAKSIS is the group described on aaksis.org. You can reach it by phone at 847-566-5992, by email at [email protected], or by mail at 3796 Ogden Lane, Mundelein, IL 60060.

What AAKSIS Does

AAKSIS describes its mission across four areas: education, support, research, and understanding. Its stated scope is 47,XXY and its variants, and its published materials also cover related sex chromosome variations — Trisomy X (47,XXX) and 47,XYY — through the family guide listed on the site.

Who It Serves

The site names three audiences:

• Individuals with XXY and related variations, who can use the support line, email, and support-group network.
• Families, who are a stated focus of the education mission and the intended readers of the organization's family guide.
• Professionals, specifically those who provide medical care and training to people with Klinefelter syndrome.

If your question is clinical — diagnosis, treatment, or fertility decisions — AAKSIS is a support and education organization, not a clinic. Use it for peer support, family-oriented information, and referrals into professional care rather than for medical advice.

How to Contact AAKSIS

The site lists the following channels:

• Support line: 847-566-5992
• Email: [email protected] (a second address, [email protected], is also listed)
• Mail: AAKSIS, 3796 Ogden Lane, Mundelein, IL 60060
• Website: aaksis.org, with sections for About Us, Education, Support, Volunteer, Donations, and Contact Us

A separate toll-free number, 888-466-5747, appears in the site's own description of the association. The site does not state hours of operation, response times, or whether either phone line is staffed live versus routed to volunteers, so treat a call as a first attempt and follow up by email if you do not reach someone.

Educational Resources on the Site

The main publication featured is Klinefelter Syndrome (47,XXY) Trisomy X (47,XXX) and 47,XYY: A Guide for Families and Individuals Affected by X and Y Chromosome Variations by Virginia Isaacs Cover, MSW. It is presented as a guide for families and individuals affected by X and Y chromosome variations and is linked from the homepage.

The site also has an Education section that points to education, medical, and advocacy groups, and a page referencing the Nolten article. The bi-annual educational conference is described as part of the support offering, but the site does not publish dates, locations, or registration details on the pages reviewed — check the site or call for the current schedule.

Practical Notes Before You Reach Out

• Be specific about your situation — whether you are an individual with XXY, a parent, or a professional — since the organization serves all three and routes inquiries differently.
• Ask about local support groups if you want in-person contact; the site says a network exists but does not list chapters.
• Donations are accepted from the XXY community as well as corporations and foundations; the site does not publish membership fees or costs for conference attendance, so confirm any costs directly.
• Verify current details on aaksis.org before relying on an address or phone number, since contact information can change.
