| Title | Possible influence of CREB1, CREBBP and CREM variants on diagnosis and treatment outcome in patients with schizophrenia. |
| Abstract | The present study explores whether some single nucleotide polymorphisms (SNPs) within CREB1 (rs2709377 and rs6740584), CREBBP (rs2239317, rs2239316, rs3025702, rs130021, rs130005, rs129974 and rs9392) and CREM (rs1148247, rs4934735, rs12775799, rs6481941 and rs16935888) could be associated with schizophrenia (SKZ) and whether they could predict clinical outcomes in Korean in-patients treated with antipsychotics. Two-hundred twenty one in-patients suffering from SKZ and 170 psychiatrically healthy controls were genotyped for 10 SNPs within CREB1, CREBBP and CREM. All patients were assessed for the severity of illness at baseline and at discharge by means of the Positive and Negative Symptoms Scale (PANSS). Our findings suggest the lack of influence of SNPs under investigation in the present study on the susceptibility to SKZ and on the response to antipsychotics. However, taking into account the several limitations of our study, further research is needed to draw more definitive conclusions. |

| Title | A network of synaptic genes associated with schizophrenia and bipolar disorder. |
| Abstract | Identification of novel candidate genes for schizophrenia (SZ) and bipolar disorder (BP), two psychiatric disorders with large epidemiological impacts, is a key research area in neurosciences and psychiatric genetics. Previous evidence from genome-wide studies suggests an important role for genes involved in synaptic plasticity in the risk for SZ and BP. We used a convergent genomics approach, combining different lines of biological evidence, to identify genes involved in the cAMP/PKA/CREB functional pathway that could be novel candidates for BP and SZ: CREB1, CREM, GRIN2C, NPY2R, NF1, PPP3CB and PRKAR1A. These 7 genes were analyzed in a HapMap based association study comprising 48 common SNPs in 486 SZ, 351 BP patients and 514 control individuals recruited from an isolated population in Northern Sweden. Genetic analysis showed significant allelic associations of SNPs in PRKAR1A with SZ and of PPP3CB and PRKAR1A with BP. Our results highlight the feasibility and the importance of convergent genomic data analysis for the identification of candidate genes and our data provide support for the role of common inherited variants in synaptic genes and their involvement in the etiology of BP and SZ. |
