This genome-wide association study examined whether parental expressed emotion moderates genetic effects on ADHD symptoms and conduct disorder in 909 family trios (600,000 SNPs genotyped). No gene-by-environment interactions reached genome-wide significance. Nominal effects were observed with 36 uncorrected interaction P-values <10⁻⁵, implicating both novel genes and candidate genes. SNPs in SLC1A1 and NRG3 emerged as candidate genes for follow-up, though the authors emphasize these findings are preliminary and require replication.
