Introduction:
MicroRNA (miRNA) single nucleotide polymorphisms (miRNA-SNPs) have been associated with pediatric acute lymphoblastic leukemia (ALL). However, since the results of these individual studies have been inconsistent, we performed a meta-analysis to help establish a statistical significance for the association between miRNA-SNPs and pediatric ALL risk. We also analyzed whether they confer susceptibility across country-specific studies by using different genetic models.
Methods:
Articles published from 2001 to 2023 were collected from PubMed and Google Scholar databases. Through MetaGenyo, the association between miRNA- SNPs and pediatric ALL risk was calculated by pooled odds ratio [ORs] and 95% CI. A subgroup analysis of pooled ORs in country-specific studies was also performed.
Results:
Based on the inclusion and exclusion criteria, 14 studies were analyzed to extract data on miR146 rs2910164, miR-196a2 rs11614913, miR-612 rs12803915 and mir-499 rs3746444. While the pooled data analysis did not reveal any association, a subgroup analysis demonstrated country-specific differences in allele frequencies of all the four miRNAs in various genetic models, implying ethnicity-based risk.
Conclusion:
Our results suggested that miRNA-SNPS can still be considered as a potential risk factor to be explored in more populations.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
