This study investigated gene polymorphisms in women with recurrent miscarriages (RM). Leptin 2549 C/A and TNF-α 238 gene variations were associated with pregnancy maintenance in RM cases.
Area of Science:
- Genetics
- Reproductive Medicine
- Immunology
Background:
- Successful pregnancy involves complex genetic and non-genetic factors.
- Previous studies on single nucleotide polymorphisms (SNPs) and recurrent miscarriage (RM) have yielded inconclusive results.
- Investigating specific gene variations may elucidate their role in pregnancy maintenance.
Purpose of the Study:
- To analyze the association of 47 single nucleotide polymorphisms (SNPs) with recurrent miscarriage.
- To identify specific genetic markers that may influence pregnancy maintenance.
- To explore the role of Leptin and TNF-α gene polymorphisms in women experiencing RM.
Main Methods:
- Genotyping of 200 women with RM and 300 control women using PCR, RFLP, and sequencing.
- Statistical analysis including multidimensional regression, classification regression tree, and logistic regression.
- Evaluation of 47 selected SNPs for their association with recurrent miscarriage.
Main Results:
- Leptin 2549 C/A (rs7799039) and TNF-α 238 (rs361525) gene variations showed a significant association with recurrent miscarriage.
- The TNF-α 238 SNP may confer a protective effect on pregnancy maintenance.
- The Leptin 2549 C/A SNP may serve as a susceptibility marker for recurrent miscarriage.
Conclusions:
- The study demonstrates an association between Leptin 2549C/A (rs7799039) and TNF-α (rs361525) gene polymorphisms and recurrent miscarriage.
- These specific gene variations may play a role in the etiology of recurrent miscarriage.
- Further research is warranted to confirm the findings and explore therapeutic implications.

Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
