Aims Mental health comorbidity is higher in those with learning disability especially who are within forensic services than the general population and diagnostic overshadowing a particular problem. Hence, all behavioural or mental related presentations often attributed to vice versa without an adequate investigation of causes disability. This case report young male mild LD longstanding problem ...

The clinical symptoms associated with chromosome 15q duplication syndrome manifest through a heterogeneous group of symptoms characterised by hypotonia, delay in motor skills and language development, cognitive and learning disabilities, autism spectrum disorder and refractory epilepsy. The late development of Lennox-Gastaut syndrome in patients with 15q11q13 duplication is a possibility that p...

The precise duplication of chromosomal DNA during each cell cycle is essential for the maintenance of genetic stability. Failure to correctly regulate chromosomal DNA replication could lead to losses or duplication of chromosome segments. The precise duplication of chromosomes is normally achieved by correct regulation of the replication licensing system. Here we review our current knowledge of...

The duplication of the short arm of chromosome 7 as de novo is extremely rare. The phenotype spectrum varies depending on the region of duplication. We report a case of de novo duplication of chromosomal region 7p21.1p22.2 in a three-year-old male child with autism who presented to the Sultan Qaboos University Hospital in Muscat, Oman, in January 2012. The patient was diagnosed with craniofacia...

7q11.23 duplication syndrome is a disease caused by duplication of a region of chromosome 7 comprising 26 genes. The first case described in the literature was reported by Somerville et al. in 2005, who described a patient with dolichocephaly, high and narrow forehead, long eyelashes, high and wide nose, short philtrum, high arched palate, dental malocclusion, retrognathia, and severe language ...

BACKGROUND Duplication of the distal part of chromosome 6p is a rare genetic syndrome. Renal involvement has been reported in the majority of patients, including a wide range of congenital abnormalities of kidney and urinary tract and, occasionally, a proteinuric glomerulopathy. CASE PRESENTATION Here, we report a 13-year-old girl with 6p25.3p22.1 duplication who presented with proteinuria in...

The presence of a duplication as well as a triplication in one chromosome is a rare rearrangement and not easy to distinguish with routine chromosomal analysis. Recent developments in array technologies, however, not only allow screening of the whole genome at a higher resolution, but also make it possible to characterize complex chromosomal rearrangements in more detail. Here we report a molec...
