Аннотация
Dup(X)(p11.22-p11.23) has been shown to be associated with intellectual disability (ID, also referred to as mental retardation). Here, we characterize a 4.64 Mb de novo duplication of the same Xp11.22-p11.23 ID region in a female, but for this reference case the diagnosis was Autism Spectrum Disorder (ASD). Besides ASD, she also had very persistent trichotillomania, anxiety symptoms and some non-specific dysmorphic features. We report the detailed clinical features, as well as refine the rearrangement breakpoints of this disease-associated copy number variation region, which encompasses more than 50 genes. We propose that in addition to ID, the phenotypic spectrum associated with dup(X)(p11.22-p11.23) can include ASD, language impairment, and/or other primary psychiatric disorders.
