High/low birth weight is associated with the development of chronic diseases in adult life. The aim of the study: To study the SNP-SNP interactions of maternal organism in matrix metalloproteinases genes and folate cycle genes and the influence on birth weight. Materials and methods: Here we genotyped ten polymorphisms: five of matrix metalloproteinases genes (rs1799750 [1G&amp;gt;2G] MMP1, rs243865 [C&amp;gt;T] MMP2, rs3025058 [6A&amp;gt;5A] MMP3, rs11568818 [T&amp;gt;C] MMP7, rs17577 [G&amp;gt;A] MMP9) and five of folate cycle genes (rs1805087 [A&amp;gt;G] MTR, rs1801394 [G&amp;gt;A] MTRR, rs1979277 [C&amp;gt;T] SHMT1, rs699517 [C&amp;gt;T] TYMS, rs2790 [A&amp;gt;G] TYMS) in 691 pregnant women. SNP-SNP interactions were investigated using a modification of the multifactor dimensionality reduction analysis (MDR) &amp;ndash; MB-MDR (Model Based Multifactor Dimensionality Reduction). The functional effects of weight-associated SNPs were assessed in silico. Results: According to the results of the study, 9 best models of intergenic interactions related to newborn weight were identified, which included all 10 studied SNPs (pperm &amp;le;0.001). The maximum number of models was set for rs11568818 MMP7 (5 models) and rs1979277 SHMT1 (6 models). The 4-locus model rs1979277 SHMT1&amp;times;rs11568818 MMP7&amp;times;rs3025058 MMP3&amp;times;rs1799750 MMP1 demonstrates the most significant association with birth weight. Conclusion: Thus, the SNP-SNP interactions of maternal organism in matrix metalloproteinases genes and folate cycle genes are associated with birth weight</p></abstract><trans-abstract xml:lang="en"><p>Background: The birth weight is one of the main parameters of the normal course of pregnancy.
