ChIP-seq isn't perfect. Even between technical replicates, you get a fair amount of variation, especially for broad marks like those you're using. It's rather uncommon to see people use H3K79me2 and H3K36me3 to determine if a gene's expressed or not. Using H3K4me3 and H3K27ac or H3ac is a more common method of marking promoters of transcribed genes. 40 ...

It is difficult to draw any conclusion without further experimentation. There may be many other factors that prevent the expression of the gene including factors like post-transcriptional regulators. Some histone modifications like the ones you are mentioning are also a bit dicey and there can be bivalent modifications too. However, if there is a strong ...
