- The effects of gender and COMT Val158Met polymorphism on fearful facial affect recognition: a fMRI studyMatthew J Kempton
Section of Neurobiology of Psychosis, Institute of Psychiatry and NIHR Biomedical Research Centre for Mental Health, King s College London, UK
Int J Neuropsychopharmacol 12:371-81. 2009..The COMT Val108/158Met polymorphism impacts on gender-related patterns of activation in limbic and paralimbic regions but the functional significance of any oestrogen-related COMT inhibition appears modest...

- Molecular genetic gene-environment studies using candidate genes in schizophrenia: a systematic reviewGemma Modinos
Department of Psychosis Studies, Institute of Psychiatry, King s College London, United Kingdom Electronic address
Schizophr Res 150:356-65. 2013..Finally, we discuss the potential of future prospects, such as new studies that combine hypothesis-based molecular genetic candidate approaches with agnostic genome-wide association studies in determining schizophrenia risk. ..
