Research M.I.N.D. Institute Washington

There is a study going on in Washington at the Nat'l.Institute of Mental Health, Child Psychiatry Branch.
The purpose of the study is to identify relationships among genes, brain, cognition and behaviour in children and young adults with sex chromosome variations.

They are looking at the following populations of sex chromosome variations: 47XXX, 49XXXXY, 48XXY, 48XXYY, 47XXYY and 47XXY.

Specifically, they are assessing the effects of extra sex chromosomal material on the volumes of the entire brain as well as its subregions (cerebral lobes, more localized regions of these lobes, and subcortical structures).
They want to better understand how these extra chromosomes influence cognition and behavior indirectly through their effects on the brain.

Finally, they would like to know how all of these phenomena change over the course of childhood, adolescence, and young adulthood.

The study began in 1999 and is expected to continue for many years.
The principal investigator is Dr. Jay Giedd, whom some of you will
recall spoke at the KS&A Conference in Kansas City, in July '04.

Currently. March 2007, there are several participants for the 47,XXX group however they would still like to have more.
