Sample GSM437639 Query DataSets for GSM437639
Status Public on Aug 08, 2009
Title Pseudoexfoliation syndrome pool - cohort 3
Sample type genomic
 
Source name Pseudoexfoliation syndrome - pool of 100 individuals
Organism Homo sapiens
Characteristics tissue: blood
Extracted molecule genomic DNA
Extraction protocol Blood samples from individuals from each phenotype definition were pooled. A single extraction was performed on each blood pool. Extraction was done according to manufacturers guidelines using the QIA-AMP DNA blood maxi kit (QIAGEN, Valencia, CA, USA). The extracted DNA was quantified by spectrophotometry.
Label Cy3, Cy5
Label protocol The Infinium assay used on the Illumina arrays is based on allele-specific single base extension using two color labeling with the Cy3 and Cy5 fluorescent dyes
 
Hybridization protocol Array data. SNPs were genotyped on pool samples using Illumina arrays. Arrays were treated according to standard protocols.
Scan protocol Arrays were scanned at Queensland Institute of Medical Research.
Description Pool of 100 individuals
Data processing Raw probe intensities were dumped from Illumina array software and analysed using methods described in Macgregor et al Nucleic Acids Research, 2006, Vol. 34, No. 7 e55.
Bead-level intensity data were analyzed. SNPs with beadscore values <-50 were excluded. Copy number variants and SNPs from the sex chromosomes were not analyzed. SNPs were also removed in the initial quality control if they had a minor allele frequency <1% in the HapMap CEU reference samples. SNPs from Illumina TOP strand exhibited different levels of pooling error to SNPs from Illumina BOTTOM strand, hence only 261887 (HumanHap550) and 375246 (1M) SNPs from the ‘BOTTOM’ strand are included in the final analysis (in estimated pooling frequencies).

Data table header descriptions
ID_REF
VALUE Estimate of allele frequency for the pool based on the raw data from all arrays. The estimate of pooling allele frequency (PAF) comes from PAF=R/(R+G) where R and G are the red and green intensities respectively. The PAFs were normalized to ensure that the mean allele frequency was 0.5 over each 'stripe' of the array.
