Mental Retardation Patients

ABSTRACT: Profiling the genomic profiles of mental retardation patients. 13 mental retardation patients were selected for detection of genomic aberrations. Patient's DNA were hybridized against Promega control on Agilent G4426B arrays and scanned with the Agilent G2505B scanner.

Array-based comparative genomic hybridization (aCGH) is a powerful tool to detect genomic imbalances in the human genome. The analysis of aCGH data sets has revealed the existence of a widespread technical artifact termed as 'waves', characterized by an undulating data profile along the chromosome. Here, we describe the development of a novel noise-reduction algorithm, waves aCGH correction algorithm (WACA), based on GC content and fragment size correction. WACA efficiently removes the wave arti ...[more]

Genotyping data from 120 trios with unexplained mental retardation

Project description:In the study we present a multicenter study in which three European diagnostic centres assessed the use of Affymetrix Mapping 500k SNP arrays for molecular karyotyping in patients with mental retardation. Each centre tested DNA from 40 patients with unexplained mental retardation together with their parents. In addition, 38 DNA samples containing known submicroscopic copy number variations (CNVs) were run for validation purposes Keywords: genomic hybridisation

Oligonucleotide microarray analysis of genomic imbalance in children with mental retardation.

Project description:The cause of mental retardation in one-third to one-half of all affected individuals is unknown. Microscopically-detectable chromosomal abnormalities are the most frequent recognized cause, but gain or loss of chromosomal segments that are too small to be seen by conventional cytogenetic analysis has been found to be another important cause. Array-based methods offer a practical means of performing a high-resolution survey of the entire genome for submicroscopic copy number variants. We studied 100 children with idiopathic mental retardation and their parents using the Affymetrix GeneChip® Mapping 100K Assay and found de novo duplications as small as 1.1 Mb in three cases, de novo deletions as small as 178 kb in eight cases, and unsuspected mosaic trisomy 9 in another case. This technology can detect at least twice as many potentially pathogenic de novo copy number variants as conventional cytogenetic analysis in people with mental retardation.

Microarray CGH (aCGH) analysis of a patient with Mental Retardation (MR)

Project description:Background: Mental Retardation occurs with the prevalence of 2%-3% of general population. Molecular karyotyping by 1-Mb resolution microarray revealed that pathological genomic imbalances were found in 14%-20% of MR. Aim: The aim of this study is to find the submicroscopic rearrangements in patient with MR using the custom BAC microarray (probe spacing at 0.75 Mb throughout the human genome). Conclusion: We identified approximate 2.0-Mb deletion on 9q33.3-q34.11 in a female with MR (Patient 1). Keywords: array CGH
