[Case report: The child- and adolescent psychiatric phenotype of a brother and sister with 16p11.2 microduplication]. / Het kinder- en jeugdpsychiatrische fenotype bij een broer en zus met de 16p11.2-microduplicatie.

16p11.2 microduplication is linked with a vulnerability for a range of psychiatric and somatic problems, with variable expression and penetration rate. We discuss the phenotypical expression of this microduplication with the case of a brother and sister. Both subjects went through child psychiatric diagnostics and treatment, where a varying degree of developmental delay and symptoms that match an attention deficit/hyperactivity disorder were observed in combination with short stature and low body mass index.
