ABSTRACT
SUMMARY OBJECTIVE To explore the association of brain-derived neurotrophic factor gene (BDNF) polymorphism with the latent cognitive endophenotype of posttraumatic stress disorder (PTSD) after major natural disasters in Hainan Province, China. METHODS A total of 300 patients with PTSD and 150 healthy controls (HC) were surveyed by psychoanalysis scale to assess their cognitive functions. Polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis (PAGE) were used to detect the BDNF gene polymorphism. RESULTS In terms of the cognitive function, the scores in the PTSD group were worse than those of the HC group (P < 0.05 or P < 0.01). There was a significant difference in the distribution of BDNF genotype and allele frequency between the two groups (P < 0.05). PTSD endophenotypes were significantly different among the BDNF genotypes in the PTSD group (P ≤ 0.01). CONCLUSION There is a statistically significant difference in the polymorphism of BDNF gene between PTSD and HC groups, and the alleles are associated with the incidence of PTSD. Thus, it may be a risk factor for PTSD.
RESUMO
RESUMO OBJETIVO Explorar a associação do polimorfismo do gene fator neurotrófico derivado do cérebro (BDNF) com o endofenótipo cognitivo latente de transtorno de estresse pós-traumático (TEPT) após grandes desastres naturais na província de Hainan, China. MÉTODOS Um total de 300 doentes com TEPT e 150 controles saudáveis (HC) foi investigado pela escala de psicanálise para avaliar as suas funções cognitivas. A reação em cadeia polimerase (PCR) e a eletroforese em gel de poliacrilamida (Page) foram usadas para detectar o polimorfismo do gene BDNF. RESULTADOS Em termos de função cognitiva, as pontuações no grupo TEPT foram piores do que as do grupo HC (P<0,05 ou P<0,01). Houve uma diferença significativa na distribuição do genótipo de BDNF e frequência do alelo entre os dois grupos (P<0,05). Os endofenótipos de TEPT foram significativamente diferentes entre os genótipos de BDNF do grupo TEPT (P≤0,01). CONCLUSÃO Existe uma diferença estatisticamente significativa no polimorfismo do gene BDNF entre o TEPT e os grupos HC, e os alelos estão associados à incidência do TEPT. Assim, pode ser um fator de risco para TEPT.
