目的:在中国儿童中验证肥胖相关基因多态性对肥胖及代谢异常的影响。方法研究对象来源于2004年北京儿童青少年代谢综合征研究( BCAMS)的3503名6~18岁学龄儿童,包括肥胖组1229名、超重组655名和正常体重组1619名。采用盐析法从外周血白细胞中提取DNA。使用ABI PrismsTM-7900实时荧光定量 PCR 仪对11个基因的多态性位点( FTO rs9939609、MC4R rs17782313、GNPDA2 rs10938397、FAIM2 rs7138803、BDNF rs6265、NPC1 rs1805081、PCSK1 rs6235、KCTD15 rs29941、BAT2 rs2844479、SEC16B rs10913469和SH2B1 rs4788102)进行分型检测。采用中国肥胖问题工作组推荐的BMI分类标准判定超重和肥胖。采用多因素分析基因多态性对儿童期肥胖相关性状的影响。采用错误发现率( FDR)方法校正多重检验。结果控制年龄、性别和青春发育期的影响后,FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G和FAIM2 rs7138803-A等位基因增加儿童BMI(β=0.352~0.747)、体脂百分比(β=0.568~1.113)、腰围(β=0.885~1.649)和腰围身高比(β=0.005~0.010)的水平( P<0.01), BDNF rs6265-G等位基因增加儿童BMI (β=0.251,P=0.020)和体脂百分比(β=0.416,P=0.040)水平。校正多重检验后,除rs6265与体脂百分比的关联消失外,其余SNP与肥胖评价指标的关联仍有意义。 FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G、FAIM2 rs7138803-A和BDNF rs6265-G等位基因增加儿童肥胖风险( OR=1.386,95%CI:1.171~1.642;OR=1.367,95%CI:1.196~1.563;OR=1.242,95%CI:1.102~1.400;OR=1.154,95%CI:1.021~1.305;OR=1.156,95%CI:1.031~1.296);其中FAIM2 rs7138803仅增加男童肥胖风险( OR=1.234,95%CI:1.043~1.460)。校正多重检验后,上述SNP与儿童肥胖的关联仍有意义。同时, GNPDA2 rs10938397-G 等位基因还增加儿童胰岛素抵抗风险( OR =1.205,95%CI:1.069~1.359),但在控制BMI后关联消失。结论 FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G和FAIM2 rs7138803-A增加儿童肥胖评价指标( BMI、体脂百分比、腰围和腰围身高比)的水平及肥胖风险,BDNF rs6265-G等位基因增加儿童BMI水平和肥胖风险;其中GNPDA2 rs10938397-G通过影响BMI可增加儿童胰岛素抵抗的风险。
目的:在中國兒童中驗證肥胖相關基因多態性對肥胖及代謝異常的影響。方法研究對象來源于2004年北京兒童青少年代謝綜閤徵研究( BCAMS)的3503名6~18歲學齡兒童,包括肥胖組1229名、超重組655名和正常體重組1619名。採用鹽析法從外週血白細胞中提取DNA。使用ABI PrismsTM-7900實時熒光定量 PCR 儀對11箇基因的多態性位點( FTO rs9939609、MC4R rs17782313、GNPDA2 rs10938397、FAIM2 rs7138803、BDNF rs6265、NPC1 rs1805081、PCSK1 rs6235、KCTD15 rs29941、BAT2 rs2844479、SEC16B rs10913469和SH2B1 rs4788102)進行分型檢測。採用中國肥胖問題工作組推薦的BMI分類標準判定超重和肥胖。採用多因素分析基因多態性對兒童期肥胖相關性狀的影響。採用錯誤髮現率( FDR)方法校正多重檢驗。結果控製年齡、性彆和青春髮育期的影響後,FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G和FAIM2 rs7138803-A等位基因增加兒童BMI(β=0.352~0.747)、體脂百分比(β=0.568~1.113)、腰圍(β=0.885~1.649)和腰圍身高比(β=0.005~0.010)的水平( P<0.01), BDNF rs6265-G等位基因增加兒童BMI (β=0.251,P=0.020)和體脂百分比(β=0.416,P=0.040)水平。校正多重檢驗後,除rs6265與體脂百分比的關聯消失外,其餘SNP與肥胖評價指標的關聯仍有意義。 FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G、FAIM2 rs7138803-A和BDNF rs6265-G等位基因增加兒童肥胖風險( OR=1.386,95%CI:1.171~1.642;OR=1.367,95%CI:1.196~1.563;OR=1.242,95%CI:1.102~1.400;OR=1.154,95%CI:1.021~1.305;OR=1.156,95%CI:1.031~1.296);其中FAIM2 rs7138803僅增加男童肥胖風險( OR=1.234,95%CI:1.043~1.460)。校正多重檢驗後,上述SNP與兒童肥胖的關聯仍有意義。同時, GNPDA2 rs10938397-G 等位基因還增加兒童胰島素牴抗風險( OR =1.205,95%CI:1.069~1.359),但在控製BMI後關聯消失。結論 FTO rs9939609-A、MC4R rs17782313-C、GNPDA2 rs10938397-G和FAIM2 rs7138803-A增加兒童肥胖評價指標( BMI、體脂百分比、腰圍和腰圍身高比)的水平及肥胖風險,BDNF rs6265-G等位基因增加兒童BMI水平和肥胖風險;其中GNPDA2 rs10938397-G通過影響BMI可增加兒童胰島素牴抗的風險。

Objective To examine the impact of single nucleotide polymorphisms in obesity-related genes on risk of obesity and metabolic disorder in childhood.Methods A total of 3 503 Chinese children aged 6 to 18 years participated in the study , including 1 229 obese, 655 overweight and 1 619 normal weight children ( diagnosed by the Chinese age-and sex-specific BMI cutoffs ).Body size parameters were assessed and venipuncture blood samples were collected after a 12-hour overnight fast.Plasma glucose , insulin and serum lipid profiles were measured.Genomic DNA was isolated from peripheral blood white cells using the salt fractionation method.A total of 11 single nucleotide polymorphisms were genotyped by TaqMan allelic discrimination assays with the GeneAmp 7900 sequence detection system ( Applied Biosystems , Foster City , CA, USA ) ( FTO rs9939609, MC4R rs17782313, GNPDA2 rs10938397, FAIM2 rs7138803, BDNF rs6265, NPC1 rs1805081, PCSK1 rs6235, KCTD15 rs29941, BAT2 rs2844479, SEC16B rs10913469 and SH2B1 rs4788102).Multiple factor analysis was performed to estimate the association between the variant and obesity-related traits.The false discovery rate ( FDR ) approach was used to correct for multiple comparisons.Results After sex, age and pubertal stage adjustment and correction for multiple testing , the rs9939609-A,rs17782313-C,rs10938397-G, and rs7138803-A alleles were associated with higher BMI (β=0.352-0.747), fat mass percentage(β=0.568-1.113),waist circumference(β=0.885-1.649) and waist-to-height ratio(β=0.005-0.010)(all P values<0.01) in Chinese children.The rs6265-G allele increased BMI(β=0.251,P=0.020).The rs9939609-A, rs17782313-C, and rs10938397-G and rs6265-G alleles were also associated with risk of obesity ( OR=1.386,95%CI:1.171-1.642;OR=1.367,95%CI:1.196-1.563;OR=1.242,95%CI:1.102-1.400;OR=1.156,95%CI:1.031-1.296).Rs7138803 was associated with risk of obesity only in boys (OR=1.234,95%CI:1.043-1.460).GNPDA2 rs10938397-G allele was associated with risk of insulin resistance(OR=1.205,95%CI:1.069-1.359), but there was no significance after adjusting for BMI.Conclusion The association of FTO rs9939609-A, MC4R rs17782313-C, GNPDA2 rs10938397-G, and FAIM2 rs7138803-A with higher BMI , fat mass percentage , waist circumference , and waist-to height ratio and risk of obesity , and BDNF rs6265-G allele may increase BMI and obesity risk in Chinese children.GNPDA2 rs10938397-G may increase the risk of childhood insulin resistance depending on BMI.
