NIH Study, twins (one or both having a SCA)
| In addition to bringing in families with boys with XYY or XXYY, we have decided to also bring in families with twins, where one or both children (age 5-25) have a sex chromosome variation (XXY, XYY, XXYY, XXXY, XXXXY,XXX). If you know of any families, please direct them to our website click here or have them send an email to Jonathan Blumenthal Thanks!
