This study aimed to investigate the association between twelve gene polymorphisms and body weight loss, 12 months after Roux-en-Y gastric bypass (RYGB) surgery. Three hundred and fifty-one obese women participated in this study. The statistical software WEKA was used to identify which gene polymorphisms were potential predictors of postoperative percentage of excess weight loss (%EWL). Our results indicate that the only gene polymorphism that predicted %EWL was rs3813929, which is related to the serotonin receptor gene (5-HT2C). Therefore, the 5-HT2C gene polymorphism rs3813929 (more specifically, the TT genotype) predicted greater %EWL 12 months after RYGB surgery among female patients.
本研究旨在调查Roux-en-Y胃旁路术（RYGB）后12个月，12种基因多态性与体重减轻之间的关联。351名肥胖女性参与了本研究。使用统计软件WEKA来确定哪些基因多态性是术后超重减轻百分比（%EWL）的潜在预测指标。我们的结果表明，唯一能预测%EWL的基因多态性是rs3813929，它与血清素受体基因（5-HT2C）有关。因此，5-HT2C基因多态性rs3813929（更具体地说，TT基因型）在RYGB手术后12个月预测女性患者有更高的%EWL。
