SHORT REPORT Detection of chromosomal imbalances in children with idiopathic mental retardation by array based comparative genomic hybridisation (array-CGH)
Chromosomal aberrations are a common cause of multiple anomaly syndromes that include growth and developmental delay and dysmorphism. Novel high resolution, whole genome technologies, such as array based comparative genomic hybridisation (array-CGH), improve the detection rate of submicroscopic chromosomal abnormalities allowing re-investigation of cases where conventional cytogenetic technique...
متن کاملWhole-genome array-CGH for detection of submicroscopic chromosomal imbalances in children with mental retardation
Chromosomal imbalances are the major cause of mental retardation (MR). Many of these imbalances are caused by submicroscopic deletions or duplications not detected by conventional cytogenetic methods. Microarray-based comparative genomic hybridization (array-CGH) is considered to be superior for the investigation of chromosomal aberrations in children with MR, and has been demonstrated to impro...

متن کامل[Non-specific X-linked mental retardation].
INTRODUCTION Non-specific mental retardation is defined by the absence of somatic, neurological, biochemical or behavioural features that characterise a particular clinical variant and accounts for a large percentage of cases of X-linked mental retardation (XLMR). Genetic linkage studies showed it to have a high rate of genetic heterogeneity. DEVELOPMENT To date, genetic linkage studies or th...
متن کاملX-linked mental retardation.
A survey of the mentally retarded children with an IQ between 30 and 55 born in a 10-year period (1955-64) and now of school age was carried out in New South Wales. The number of propositi who had a similarly affected sib of the same sex was ascertained; 58 boys had a similarly affected brother(s) and 22 girls had a similarly affected sister(s). It is suggested that the excess of affected broth...
