Serum MIF protein levels and genetic variants (MIF rs1049829 and rs755622) were evaluated in a case–control cohort of 133 treatment-naïve Egyptian breast cancer patients and 126 healthy controls. Results show higher serum MIF in cases, diagnostic performance at a defined cut-off, links with progesterone receptor status, and an association of rs1049829 with a protective effect. The findings support serum MIF as a promising tumor marker and rs1049829 as a candidate protective variant.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/the-clinical-signature-of-genetic-variants-and-serum-levels-of-macrophage-migration-inhibitory-factor-in-egyptian-breast-cancer-patients-abstract-and-study-results/333885/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/the-clinical-signature-of-genetic-variants-and-serum-levels-of-macrophage-migration-inhibitory-factor-in-egyptian-breast-cancer-patients-abstract-and-study-results/333885.png","ImageObject",300,407,{"name":42,"@type":43},"Miles","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-23","2026-09-21",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What is the purpose of this study on MIF in breast cancer?","Question",{"text":62,"@type":63},"To evaluate the clinical value of serum MIF levels and to determine the association between MIF rs1049829 and rs755622 variants and serum MIF levels and breast cancer development.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"How were serum MIF levels and genotypes measured?",{"text":67,"@type":63},"Serum MIF protein levels were quantified using ELISA, and genotyping used the TaqMan allelic discrimination assay.",{"name":69,"@type":60,"acceptedAnswer":70},"What were the key findings regarding serum MIF and breast cancer risk?",{"text":71,"@type":63},"Breast cancer cases showed significantly higher serum MIF levels than controls, with reported sensitivity and specificity at a specified cut-off.

However, conflicting findings on the relationship between MIF polymorphisms and breast cancer (BC) have been reported in earlier research. We investigated the clinical value of serum MIF levels and the association between MIF rs1049829 and rs755622 variants with their serum levels and propensity to develop BC.  \nMethods A total of 133 treatment-naïve Egyptian BC females and 126 apparently healthy controls were matriculated in this case–control study. The serum MIF protein levels were quantified by ELISA, whereas the genotyping was executed utilizing the TaqMan® allelic discrimination assay.  \nResults A significant increase in the serum MIF level in BC cases was observed in comparison to control subjects (P \u003C 0.0001), with a diagnostic potential to discriminate BC with 92.5% sensitivity and 73.7% specificity at a cut-off value >9.47 ng/mL. Besides, a significant difference in serum MIF level was observed in BC cases with progesterone receptor (PR) negativity compared to those with PR positivity (P = 0.046). Moreover, a significant association was depicted between the rs1049829 variant of MIF gene and the protective effect against BC meanwhile the rs755622 variant demonstrated no significant link with BC risk.  \nConclusions This study revealed that serum MIF levels may be regarded as a promising serum tumor marker for BC. Also, the rs1049829 variant of the MIF gene is considered a protective candidate against BC.  \n* Ahmed A.
