Unique functional annotation clusters of genes from arsenic and control datasets.

For category ranking and analysis of biological terms in DAVID, the first 3000 regions of enrichment were filtered by absolute distance of ≤1 kb from the TSS. The final gene lists submitted for analysis consisted of 1757 and 1803 official gene symbols in the arsenic and control groups, respectively. For each of the lists unique Molecular Function and Biological Process terms are generated by satisfying two criteria - fold enrichment >1.5 and statistically significant Benjamini factor
