^aGene symbol according to HUGO Gene Nomenclature Committee (http://www.genenames.org/).

^bCpG site ID assigned by Illumina.

^cNumber of individuals with ASE and low or high methylation levels (beta-value <0.25 or >0.75).

^dNumber of individuals with ASE and intermediate methylation levels (beta-value between 0.25 and 0.75).

^eMedian ASE-level for individuals with low or high methylation levels (beta-value <0.25 or >0.75).

^fMedian ASE-level for individuals with intermediate methylation levels (beta-value between 0.25 and 0.75).

^gP-value for the difference in ASE level between the groups of samples with intermediate and low or high methylation levels calculated using a one-sided Mann-Whitney test.

^hP-value computed by permuting the methylation groups and recalculating the median ASE levels 5000 times.
