PITPNM3 and attention deficit-hyperactivity disorder: Another one of these CpGs (cg11237284) was located proximal (i.e., 500 bases upstream) to the ADHD-associated SNP (rs1105916) in PITPNM3.This overlap in findings from the current and prior EWAS and GWAS studies suggests that both genetic and epigenetic processes likely contribute to risk for attention problems, though their relative contributions is not yet known.
