Abstract | Rearrangements of 22q11.2 region, most often deletions and duplications, are responsible for multiple congenital disorders. These rearrangements are involved in syndromes that share some phenotypic similarities. To date, 22q11.2 triplication remains very rare, with few cases described in the literature. Here, we report for the first time the clinical, neurocognitive, social cognition and psychiatric properties of a 6-year-old child with 22q11.2 triplication, in comparison with a patient with 22q11.2 duplication and 16 cases of patients with 22q11.2 deletion. Chromosomal region 22q11.2 seems to be a critical locus for sociability and attentional skills and rearrangements could be interpreted as a predisposing factor for the development of psychotic symptoms (22q11.2 deletion), a protective factor (22q11.2 duplication) or a tendency factor for hypersociability (22q11.2 triplication). |
