Prediction of clinical reactivity in food sensitized individuals from blood DNA methylation profiles
Ontology highlight
ABSTRACT: Genome wide DNA methylation profiling study of PBMC from 71 unique primary patient blood samples. The Illumina Human Methylation 450k array was used. 29 challenge proven food allergy, 29 sensitized but oral tolerant, 13 non food allergics Mixture of food allergy phenotypes (egg allergic (15), peanut allergic (14)), food sensitization phenotypes (egg sensitized (14), peanut sensitized (15)). 4 samples had technical replicate hybridzations. Bisulphite converted DNA from the 75 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip v1.2. Technical replicates were combined during processing, resulting in normalized Beta values for 71 unique primary patient blood samples.
