The percentage of distribution for allele G was 88.7%, and 78% in controls and cases respectively (<em>p</em> = 0.005). The risk of RPL was decreased by 60% in carriers of allele G (OR = 0.4, 95%CI: 0.2–0.8, <em>p</em> = 0.003). Besides, the homozygote genotype GG (OR = 0.5, 95%CI: 0.28–0.95, <em>p</em> = 0.031), was linked with decreased risk for RPL. The homozygous GG genotype and G allele were associated with decreased risk of RPL in Egyptian females.</p></div>","PeriodicalId":38190,"journal":{"name":"Meta Gene","volume":"30 ","pages":"Article 100955"},"PeriodicalIF":0.7,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mgene.2021.100955","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46961965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
