Sex Chromosome Aneuploidy

Ongoing Study at NIMH

X-Y Graphic

The Child Psychiatry Branch of the National Institute of Mental Health is conducting a study of the effects of sex chromosomes on human brain development. This study examines sex chromosome aneuploidy syndromes, which arise due to carriage of an atypical number of X and/or Y-chromosomes beyond the typical female (XX) or male (XY) complement.

Recent analyses within this study have focused on (i) better understanding the changes in cognition, brain anatomy, and risk for mental illness that can accompany each sex chromosome aneuploidy syndrome, and (ii) combining information across various sex chromosome aneuploidy syndromes to specify the overlapping and distinct effects of X and Y-chromosome dosage on brain development.
