Abstract

The Xp22.31 segment of the short arm of the human X chromosome is a region of high instability with frequent rearrangement. The duplication of this region has been found in healthy people as well as in individuals with varying degrees of neurological impairment. The incidence has been reported in a range of 0.4-0.44% of the patients with neurological impairment. Moreover, there is evidence that Xp22.31 duplication may cause a common phenotype including developmental delay, intellectual disability, feeding difficulty, autistic spectrum disorders, hypotonia, seizures, and talipes. We report on a patient with microcephaly and trigonocephaly, moderate intellectual disability, speech and language delay, and poor social interaction in addition to minor but atypical dysmorphic features. This report provides further insight into the pathogenicity of the Xp22.31 duplication by extending knowledge of its clinical features. This case, in association with those reported in the literature, indicates that the Xp22.31 duplication may contribute to cause pathological phenotypes with minor facial dysmorphisms, microcephaly, and intellectual disability as main features.
