▶Does parental expressed emotion moderate genetic effects in ADHD? an exploration using a genome wide association scanAssociationN=909Edmund J.S. Sonuga‐Barke et al.(2008)· American Journal of Medical Genetics Part B: Neuropsychiatric Genetics
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.
About HTR2A
This gene encodes one of the receptors for serotonin, a neurotransmitter with many roles. Mutations in this gene are associated with susceptibility to schizophrenia and obsessive-compulsive disorder, and are also associated with response to the antidepressant citalopram in patients with major depressive disorder (MDD). MDD patients who also have a mutation in intron 2 of this gene show a significantly reduced response to citalopram as this antidepressant downregulates expression of this gene. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
