This is a companion package for SNPhood and provides additional example datasets for the SNPhood package. The datasets in the SNPhoodData package are used in the SNPhood vignette and provide “real-world” examples for exploring the molecular neighbourhood of SNPs using allele- and genotype-specific analyses.
SNPhoodData 1.35.0
In a recent study we have identified thousands of quantitative trait loci (QTLs) for different histone marks using individuals from the Yoruban (YRI) population [2]. In our case, histone (h)QTLs are SNPs for which the genotype correlate with the variation of histone H3K27ac signal within a H3K27ac peak. Here we will investigate how many of these previously identified hQTLs show allele-specific binding in individuals from a different population (CEU; European).
The example dataset consists of the following files:
