The UC Davis M.I.N.D. Institute presents the first national conference on Trisomy X and XYY syndromes for patients, parents and professionals to raise awareness and highlight promising research and successful interventions. Trisomy X and XYY syndromes are X and Y chromosome variations that together affect one in every 900 live births. Conference presentations will fill in the gaps of knowledge of these conditions so physicians, clinicians, educators, speech therapists, occupational therapists and other healthcare professionals can together better address patient needs. Small-group discussions cover social skills, problem behaviors, Individualized Education Plan (IEP) strategies and other concerns common to parents.

Trisomy X syndrome affects females who have three X chromosomes instead of the usual two. It is the most common X-chromosome disorder in females. Symptoms vary and can include tall height, speech and language delays, behavioral problems, delayed puberty and infertility. XYY syndrome is a condition in which males have two Y chromosomes rather than the usual one. Boys with the syndrome may exhibit increased height, problems with motor coordination, hyperactivity and learning disabilities.
