·综述·MTHFRC677T基因多态性与抑郁症关系的研究进展王强,赵鹏,曹秋云,沈迪文,张宇哲,姚志剑摘要:抑郁症病因复杂,遗传是重要因素之一,其中MTHFRC677T基因多态性因涉及同型半胱氨酸(Hcy)和叶酸代谢而参与抑郁症等精神类疾病的发生。本文综述了MTHFRC677T基因多态性与抑郁症发病、症状和疗效的关系,以及其对抑郁症脑影像的影响等,总结了目前MTHFRC677T基因多态性与抑郁症关系的研究进展。希望以此为深入理解抑郁症病理机制提供新的视角,也为未来抑郁症研究提供新的思路。关键词:MTHFRC677T基因多态性;抑郁症;同型半胱氨酸;叶酸中图分类号:R7494文献标识码:A文章编号:10053220(2023)04032503ResearchprogressontherelationshipbetweenMTHFRC677TgenepolymorphismandmajordepressivedisorderWANGQiang,ZHAOPeng,CAOQiuyun,SHENDiwen,ZHANGYuzhe,YAOZhijian.DepartmentofMedicalPsychology,NanjingDrumTowerHospital,AffiliatedHospitalofMedicalSchool,NanjingUniversity,Nanjing210029,ChinaAbstract:Theetiologyofmajordepressivedisorder(MDD)iscomplex,andgeneticsisoneoftheimportantfactors.Amongthem,theMTHFRC677TgenepolymorphismisinvolvedintheoccurrenceofmentaldisorderssuchasMDDduetoitsinvolvementinhomocysteine(Hcy)andfolatemetabolism.ThisarticlereviewstherelationshipbetweenMTHFRC677Tgenepolymorphismandtheonset,symptoms,andefficacyofMDD,aswellasitsimpactonbrainima...
