Developmental trends of communicative skills in children with chromosome 14 aberrations.

The increase of communicative skills in children with chromosome 14 aberration is very slow. We need to consider the children's characteristics, in terms of type of chromosome aberration, level of intellectual disability and presence/absence of autistic traits, to predict their possible linguistic outcomes and to give a more realistic expectation to their parents. What is known: • The communicative skills of children with chromosome 14 aberrations are usually impaired. • The presence of autistic traits is frequent in these children. What is new: • The increase of communicative skills in children with chromosome 14 aberrations is very slow. • The level of intellectual disability and the presence/absence of autistic traits appeared to have a role in predicting the possible linguistic outcomes in children with chromosome 14 aberrations.
