Estudo de associação entre genes do sistema dopaminérgico e esquizofrenia / Study of association between genes of the dopaminergic system and schizophrenia

Cordeiro Junior, Quirino 16 August 2007 (has links)
Evidências de estudos genético-epidemiológicos têm demonstrado a existência de um fator de risco genético para o desenvolvimento da esquizofrenia. Na presente Tese, um total de 245 pacientes com esquizofrenia e 834 controles foi selecionado com o objetivo de investigar a diferença na distribuição de alelos e genótipos de seis polimorfismos de quatro diferentes genes do sistema dopaminérgico nesses dois grupos: 1. TaqI A1/A2 do DRD2 - rs1800497; 2. -141C (Ins/Del) do DRD2 - rs1799732; 3. Ser-9-Gly do DRD3 - rs6280; 4. VNTR da região 3´ não-codificadora do SLC6A3; 5. A1343G do SLC6A3 - rs6347; 6. A/G da região 3´ não-codificadora do COMT - rs165599. Os resultados mostraram associação dos polimorfismos -141C (Ins/Del) do DRD2 (rs1799732) e A1343G do SLC6A3 (rs6347) com esquizofrenia na amostra investigada. / Evidences from genetic epidemiological studies have demonstrated the existence of a genetic risk factor for schizophrenia. In the present work a total of 245 schizophrenic patients and 834 controls were selected to investigate differences in the allelic and genotypic distribution of six polymorphisms from four different genes of the dopaminergic system between the groups: 1. TaqI A1/A2 of the DRD2 - rs1800497; 2. -141C (Ins/Del) of the DRD2 - rs1799732; 3. Ser-9-Gly of the DRD3 - rs6280; 4. VNTR in the 3\'-untranslated region of the SLC6A3; 5. A1343G of the SLC6A3 - rs6347; 6. A/G in the 3\'-untranslated region of the COMT - rs165599. The results have found an association of the polymorphisms -141C (Ins/Del) of the DRD2 (rs1799732) and A1343G of the SLC6A3 (rs6347) with schizophrenia in the investigated sample.
