It has become obvious from epidemiological studies in families of patients affected or from twin studies, that most psychiatric disorders are in part genetically determined. Genetics have raised incredible hopes that the complex nature of psychiatric disorders might be unravelled. However, progress in psychiatry genetics have met major difficulties that have hampered psychiatry taking advantage of the new technologies as compared to other fields, such as neurology. In this non-exhaustive review… 
Interactions gènes/environnement dans la schizophrénie
Troubles psychiatriques, génétique ou environnement : vers la fin du débat ?
Bien que les donnees d’epidemiologie aient clairement montre l’agregation des principaux troubles psychiatriques au sein de certaines familles, l’identification des genes impliques se heurte a leur


Schizophrenia: a review of genetic studies.
The development and utilization of stringent, reliable diagnostic criteria, together with the advent of modern family, twin, and adoption paradigms, demonstrate the importance of genetic factors in understanding the familial basis of the disorder.

The Genetics of Adult-Onset Neuropsychiatric Disease: Complexities and Conundra?
This work has identified a number of candidate susceptibility loci/genes associated with inherited susceptibility to late-onset neurodegenerative diseases, schizophrenia, and bipolar disorder that are likely to interact with each other (and with nongenetic factors) to modulate susceptibility and/or disease phenotype.
The genes for schizophrenia: Finally a breakthrough?
Though credible evidence is available for all of these genes, it is strongest for NRGI andDTNBPI, and further studies, particularly exhaustive analyses of all polymorphisms at each locus, meta-analyses, and investigations of the likely function of risk alleles (variants) are desirable.
Genetic abnormalities of chromosome 22 and the development of psychosis
Although a number of genes have been implicated as possible schizophrenia susceptibility loci, further confirmatory studies are required, and compelling evidence that haploinsufficiency of TBX1 is likely to be responsible for many of the physical features associated with the deletion is provided.
Molecular genetics of autism spectrum disorder
Recent studies in families with autism spectrum disorder have identified uncommon occurrences of a novel genetic syndrome caused by disruptions of the NLGN4 gene on chromosome Xp22, and the contributions of multiple approaches to identifying the genes of interest are highlighted.
Location of a major susceptibility locus for familial schizophrenia on chromosome 1q21-q22.
A genome-wide scan for schizophrenia susceptibility loci in 22 extended families with high rates of schizophrenia provided highly significant evidence of linkage to chromosome 1 (1q21-q22), with a maximum heterogeneity logarithm of the likelihood of linkage (lod) score of 6.50.
