Project description:This series represent the data set belonging to the publication by de Vries et al. Diagnostic genome profiling in mental retardation. American Journal of Human Genetics, vol 77: 606-616 (2005). In this study 100 patients with unexplained mental retardation were analyzed for DNA copy-number changes using a tiling-resolution genomewide microarray containing 32,447 BACs. Keywords: CGH
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.

Project description:In this study 405 patients with unexplained mental retardation and 89 unaffected parents were analyzed for DNA copy-number changes using a tiling-resolution genomewide microarray containing 32,447 BACs. This series contains 367 slides from 315 individuals previously not reported, plus an additional 239 slides from 179 individuals previously reported in the series GSE3191. Keywords: array CGH
Project description:We report a deletion on 11q13.3-q13.4 in one patients with severe mental retardation. We analyzed a patient with mental retardation and the related parents with a whole genome SNP Array.
Project description:Profiling the genomic profiles of mental retardation patients. 13 mental retardation patients were selected for detection of genomic aberrations.
