A new article published in Autism Research compares the behavioral characteristics of boys with MECP2 Duplication Syndrome to the behavioral characteristics of boys with idiopathic autism (i.e., autism that is not known to be secondary to some other condition). The study looks looks at irritability, lethargy, social behavior, and restricted, repetitive behaviors. Four of ten boys diagnosed with MECP2 duplications had previously been diagnosed as falling within the broad class of Autism Spectrum Disorders. Overall, boys with MECP2 Duplications were a little more social and exhibited less irritability, but were very similar to the idiopathic autism group.
I don’t think the results of this study will come as a surprise to families, who have often comment that they can see some autistic traits in their MECP2 Duplication Syndrome kids, but feel like they are more social than they would expect from in an autistic child
