Because we know it's impossible for one organization to be everything to everyone, we've provided information here about other organizations and support groups for individuals with X&Y Chromosome variations and their families. Note that entries listed under "Organizations" often also include information about additional support groups.

Check out other resources on this website. AXYS supports multiple forums for individuals with X&Y chromosome variations and their families. Also, be sure to also look in our library for articles regarding X&Y Chromosome variations as well as articles on subjects affecting individuals with X&Y chromosome variations. 


  • The eXtraordinarY Kids Clinic at Children’s Hospital Colorado
    This is the world’s only multidisciplinary clinic dedicated to X and Y chromosome variations.  




  • The XXYY Project - The mission of the XXYY Project is to build the capacity of parents and service providers to assist males with XXYY in leading purposeful, productive lives.

Sex Development: An Overview

KS&A celebrates the diversity of the human family; including sex and gender, skin color, ethnicity, religion, sexual orientation, gender identity, age, socioeconomic status, physical characteristics, and mental abilities.  While the majority of 47,XXY individuals we serve identify as male, a minority identifies as “intersex” or another gender.  Many also consider themselves as “being XXY” rather than “having XXY.”  
The organizations listed below are separate from KS&A and each has a unique mission focused on intersex.  KS&A respects these organizations, but we also recognize that some of their positions and interpretations of information may not align with KS&A's.
If you are reading this page, perhaps you have questions about gender identity.  If so, we encourage you to explore gender counseling.
