摘要 目的探讨瘦素(LEP)基因单核苷酸多态性位点rs3828942与土家族儿童单纯性肥胖的相关性。方法用聚合酶链反应-限制性片段长度多态性技术分析208例单纯性肥胖儿童和201例健康对照儿童的LEP基因型及等位基因频率分布状况,同时测定血脂和血红蛋白(Hb)水平。结果肥胖和健康对照组LEP基因突变型(AA)、杂和型(AG)及野生型(GG)基因型频率分别为57.2%、34.6%、8.2%和54.2%、36.3%、9.5%,两组等位基因频率分别为74.5%、25.5%和72.4%、27.6%,两组基因型与等位基因频率差异均无统计学意义(P>0.05);肥胖与健康对照组LEP基因型频率在性别分层中差异均无统计学意义(P>0.05)。肥胖组的三酰甘油和Hb水平高于健康对照组,差异有统计学意义(P<0.05),肥胖组AA型Hb高于GG型与AG型,差异有统计学意义(P<0.05)。结论 LEP基因rs3828942位点多态性与土家族儿童单纯性肥胖及血脂水平无关联,但对单纯性肥胖儿童Hb水平有一定影响。
