EGAD00001004268	Samples from 149 trios from the Saguenay-Lac-Saint-Jean asthma familial cohort were all sequenced using a custom capture panel developed by our group, followed by next-generation sequencing. This custom capture panel covers around 3% of the genome, including coding and non-coding immune regulatory regions. We inferred the sequence in the non-sequenced siblings who were part of the same families as the trios and we imputed the sequence using IMPUTE2 in the whole cohort.		1214
EGAD00010001593	This dataset includes raw data (.idat) for the Illumina Human450k beadchip and methylation levels (.txt files). Methylation level were treated for normalization and background substraction. We removed probes with at least one of the following characteristics: (1) weak signal (pâ€‰>â€‰0.01) (2128 CpG sites), (2) SNP-enriched sites (4100 sites), (3) out of a CpG context (not on a CG) (3149 sites), or (4) located on sex chromosomes (11,129 sites). A total of 465,071 CpG sites were analyzed initially. Signal was then normalized, first by scaling to the internal controls using the methylumi R package, then by applying the method of subset-quantile within array normalization (SWAN) implemented in the minfi R package.
