Abstract
Autism is a neurodevelopmental disorder presenting in the first 3 years of life. Deficits occur in the core areas of social communication and interaction and restricted, repetitive patterns of behavior, interests or activities. The causes of autism are unknown, but clinical genetic studies show strong evidence in favor of the involvement of genetic factors in etiology. Molecular genetic studies report some associations with candidate genes, and candidate regions have emerged from several genome-wide linkage studies. Here, we report a clinical case of autism in a 6-year-old boy with double duplication on 10q11.22q11.23 with ASD (Autism Spectrum Disorder), intellectual disability, developmental delay, hypotonia, gross-motor skills deficit, overgrowth and mild dysmorphic features. In the literature, only five cases of ASD with 10q11.21q11.23 duplication are reported. This is the first extensive clinical description of an ASD subject with 10q11.22q11.23 duplication. Our findings suggest that 10q11.21q11.23 microduplication could represent a copy number variant that predisposes to autism.

Proximal 10q duplication in a child with severe central hypotonia characterized by array-comparative genomic hybridization: A case report and review of the literature. Exp Ther Med 2014; 7:953-957. [PMID: 24669257 PMCID: PMC3964923 DOI: 10.3892/etm.2014.1520] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2013] [Accepted: 01/08/2014] [Indexed: 11/05/2022] Open
Abstract
Proximal 10q duplication is a well-defined but rare genetic syndrome. Duplication of proximal segments of the long arm of chromosome 10 results in a pattern of malformations, which are distinct from those of the more common distal 10q trisomy syndrome. The present study describes the case of a boy with phenotypic abnormalities (severe central hypotonia, mild ataxia, moderate developmental delay and mild dysmorphic features), due to duplication of chromosome region, 10q11.21→q11.22, which was characterized by the array-comparative genomic hybridization (CGH) technique. The phenotypic findings were compared with those in eight additional similar published cases. Major similarities have emerged, suggesting a likely minimal critical region. However, only detailed characterization of additional cases may provide firm conclusions.

Abstract
Herein we describe a unique case of partial proximal 10q trisomy presenting biliary atresia, anal anteposition and cardiac malformation. The 10q duplication was confirmed by G banding on prophase chromosomes. A review of the literature confirmed that the patient displayed characteristic dysmorphic features of the recently defined partial proximal trisomy 10q syndrome and emphasized the interindividual variability of visceral malformations.

Abstract
A 7-year old female with global cognitive impairment, short attention span, hyperactivity, impulsivity, and many compulsive behaviors was referred to the Genetics Clinic. Height was below the 5th centile and weight was at the 5th centile while head circumference was at the 50th centile. Minor anomalies included bluish sclera, low set and slightly posteriorly rotated auricles and a narrow palate with marked overbite. There was no significant family history. Chromosome analysis showed an unbalanced, mosaic female karyotype consisting of three cell lines: 46,X,+r[46]/45,X[37]/45,X,dup(1)(q11q21.3) [17] de novo.ish r(X)(DXZ1+,XIST+). Expression of XIST was observed in cDNA from the patient, suggesting the presence of an inactive X chromosome. Inactivation was confirmed by detection of a methylated allele of androgen receptor. This methylated allele was under-represented in undigested DNA, consistent with it arising from the r(X) which was present in only a minority of the patient's cells. The clinical phenotype of the tiny r(X) syndrome in our patient is obviously further influenced by mosaicism for the dup(1). Few cases of duplication of the proximal portion of chromosome 1 have been reported. Of these, the duplication either was present in all cells or involved different band regions so that a direct comparison would be difficult. However, the lower percentage of mosaicism for the dup(1) in our patient would suggest a milder influence on the clinical phenotype.

Abstract
We describe a family in which two siblings exhibited developmental delay, reduced muscle tone and mild muscle weakness. Cytogenetic evaluation demonstrated that both children had a tandem duplication of a small portion of the long arm of chromosome 10 [46,XX or XY,dir dup(10)(q24.2-->q24.3)], inherited from their clinically normal mother, who was found to be mosaic for the duplicated chromosome 10. Fluorescence in situ hybridization approaches, including total chromosome painting and the use of regional specific cosmid probes, were used to confirm the chromosome 10q origin of the duplicated material. This is the smallest confirmed duplication of this portion of chromosome 10 reported to date.

Abstract
We report on a girl with a partial duplication of the proximal part of the long arm of chromosome 10, confirmed by chromosome painting. The phenotypic findings are compared to those found in six other published cases with the same karyotype. Recognition of a specific partial proximal trisomy 10q syndrome seems to be possible, consisting of mild to moderate developmental delay, postnatal growth retardation, microcephaly, prominent forehead, small and deep set eyes, epicanthus, upturned nose, bow shaped mouth, micrognathia, thick and flat helices of the ears, and long, slender limbs. Severe ocular malformations are possibly part of the syndrome. No major phenotypic differences were seen between patients with a duplication of segment 10q11-->10q22 and patients with a duplication of 10q21-->10q22.

Abstract
This report summarizes the clinical and cytogenetic findings in a 16-year-old moderately mentally retarded girl with 10q11.2----10q22 duplication. The phenotypic findings are identical to those found in one other patient with the same autosomal duplication. These data suggest that proximal 10q11.2-10q22 duplication is associated with a specific clinically recognizable syndrome.

Abstract
A boy with bilateral colobomas, preauricular pits, and developmental delay had a 46,XY,22q+ karyotype. His parents had normal chromosomes. The abnormality of 22q was interpreted as a de novo tandem duplication of 22q11.1----q11.2. Although no anal abnormality was identified, his manifestations are otherwise consistent with those of the cat-eye syndrome. Blood marker results and the levels of galactosidase-2, galactosidase-B and arylsulfatase-A, which are known to be coded on 22q, are normal.

Abstract
Tandem repeats of chromosome material can arise as inverted or as direct duplications. Such duplications of the X chromosome are instructive regarding X-linked genetic determinants of phenotype. We describe a 40-year-old woman with a direct duplication Xq13.3 to Xq27.2, short stature, gonadal dysgenesis, and secondary amenorrhea. Comparison of her phenotype with that of two other women with a direct duplication of part of Xq confirms the existence of statural determinants within the region X13 to Xq21, determinants of ovarian function within X22 to X27, and the X inactivation center within or proximal to band Xq13.3. In humans, direct duplications are more frequent than inverted, but both forms are rare. The mean age of parents is normal in subjects with direct duplications, but is advanced in subjects with inverted duplications. An inverted duplication can arise from a three-break rearrangement that includes a U-type exchange; a similar origin (two breaks and a U-type exchange) and a parental age association can be postulated for dicentric inverted duplications including dicentric isochromosome X.

Abstract
A girl with mental retardation and the facies associated with the distal 10q duplication syndrome was found to have a tandem duplication of 10q24 to 10q26. This was confirmed by gene dosage studies of glutamic oxaloacetic transaminase 1. The clinical features of this patient are compared with those of other reported cases of the distal 10q duplication syndrome with duplication-deficiency karyotypes due to familial reciprocal translocations or inversions or with tandem duplication of a more proximal region of 10q. Reports of tandem duplications in man and possible mechanisms of origin are discussed.
