Known NZ XXY'ers
Recently diagnosed? Let us know – we have groups of XXY’ers and parents who meet up online to chat and support each other. We also arrange in-person meetings and events from time to time.
Note that we only know of 128 in New Zealand, more may ‘know’ they are XXY. We also happily have XXXY’ers and others as part of our network.

- Breast cancer awareness for XXY’ers
47,XXY is one of the most common chromosome karyotype structures after XY & XX. It happens somewhat randomly between 1 in 500 and 1 in 1,000 newborn males.
Technically, being XXY is not rare; however, it is rarely discovered.
We are happy to champion Rare Disorders NZ.
