Depression is one of the most prevalent mental health disorders worldwide, affecting a significant proportion of the global population. Its etiology is complex and influenced by the interaction of environmental factors and genetic variations. In Mexico, it has been reported that 41.3% of the population exhibits depressive symptoms. Previous studies have suggested that susceptibility to depression may be associated with the C-1019G (rs6295) polymorphism in the serotonin 1A (5-HT1A) receptor gene.
In this study, we aimed to evaluate the association between the C-1019G polymorphism and depressive symptoms in a rural Mexican population.
Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), we examined the effect of C-1019G on depression symptoms, as evaluated by the Beck Depression Inventory. Data were obtained from 83 volunteers; individuals with depressive symptoms and those with a healthy mood were compared.
The results showed that the homozygous C/C genotype was found significantly more frequently in the control group than in individuals with depressive symptoms, particularly among men, and is thus associated with a decreased risk of depressive symptomatology.
The C/C genotype could protect against susceptibility to developing depressive symptoms in a rural population in Mexico.
抑郁症是全球最常见的心理健康障碍之一,影响着很大一部分全球人口。其病因复杂,受环境因素和基因变异相互作用的影响。在墨西哥,据报道41.3%的人口表现出抑郁症状。先前的研究表明,抑郁症易感性可能与血清素1A(5-HT1A)受体基因中的C-1019G(rs6295)多态性有关。
在本研究中,我们旨在评估墨西哥农村人口中C-1019G多态性与抑郁症状之间的关联。
使用聚合酶链反应-限制性片段长度多态性(PCR-RFLP),我们通过贝克抑郁量表评估了C-1019G对抑郁症状的影响。数据来自83名志愿者;比较了有抑郁症状的个体和情绪健康的个体。
结果显示,纯合子C/C基因型在对照组中出现的频率明显高于有抑郁症状的个体,尤其是在男性中,因此与抑郁症状的风险降低有关。
C/C基因型可能对墨西哥农村人口患抑郁症状的易感性具有保护作用。
