A patient with a rare interstitial deletion of chromosomal band 2q33.2q33.3 is described. The clinical features resembled the 2q33.1 microdeletion syndrome (Glass syndrome), including mental retardation, facial dysmorphism, high-arched narrow palate, growth deficiency, and speech delay. The chromosomal aberration was characterized by whole genome BAC aCGH. A comparison of the current patient and Glass syndrome features revealed that this case displayed a relatively mild phenotype. Overall, it is suggested that the deleted region of 2q33 causative for Glass syndrome may be larger than initially suggested.

We report a 9-year-old girl with 3 Mb interstitial deletion of chromosome 15q24 identified by oligonucleotide array comparative hybridization. She is of Chinese ancestry and shared some typical features of previously reported 15q24 deletion cases such as mild dysmorphism with developmental and speech delay. She also had mild hearing loss that was reported in one other case. We compared all 19 cases that are identified from array-CGH. The deletion occurred within an 8.3 Mb region from 15q23 to 15q24.3. The minimum overlapping deleted region is less than 0.5 Mb from 72.3 Mb to 72.7 Mb. The functions of the nine annotated genes within the region and how they might contribute to the microdeletion phenotype are discussed.

IntroductionX-linked mental retardation (XLMR) is a common, clinically complex and genetically heterogeneous disease arising from many mutations along the X chromosome. Although research during the past decade has identified >90 XLMR genes, many more remain uncharacterized. In XY males, duplication of any part of the X chromosome leads to functional disomy of the corresponding genes.ObjectiveIn this paper we present the case of a boy with a syndrome of Xq28 duplication. Methods: We present a 6 years old boy, admitted in the Department of Pediatric Psychiatry for evaluation. He presented sever mental retardation, autistic features, speech delay, hyperkinesia, and dysmorphic features (high forehead, partial palpebral ptosis, small nose, carp-shaped open mouth, micrognathia), recurrent infections. Cerebral MRI was normal. Genetic investigations, including katyotype with GTG banding and array-CGH, were performed.ResultsArray-CGH indicated a dup(X)(q28) of less than 1.5 Mb. There were 15 duplicated genes, including MECP2 gene, which is involved in autism and mental retardation.ConclusionsDuplications at Xq28 are often associated with autistic features/non-syndromic MR; alterations in MECP2 gene (duplicated in our patient) are described in Rett syndrome or as a specific phenotype. The alteration occurring at Xq28 band is responsible for the patient’s phenotype. Clinical manifestation of this child will be compared with those of other patients with the same duplication previously described to further delineate this syndrome.
