TRIXY Center of Expertise
The multidisciplinary team of researchers, clinicians and medical practitioners within TRIXY ensures that important knowledge is gathered about vulnerabilities in individuals with an extra X or Y chromosome, in the field of physical, neurocognitive, emotional and social development, and risk for learning problems and behavioral problems. We need this knowledge to recognize early signs of developmental risks, provide psychoeducation, and to be able to provide the best support for children during their development, and to identify and develop interventions that are in line with the needs of children with X and Y chromosome trisomies.
