The expression of m6A\u2010related genes was analyzed across all samples. Using the GSVA and CIBERSORT packages in R, we developed a diagnostic model based on the m6A gene\u2013protein interaction network, conducted enrichment analysis of hub genes, and assessed the correlation between these genes and immune cell infiltration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Analysis of data sets GSE137684 and GSE804322 identified variable expression patterns among three categories of m6A genes. A diagnostic model centered on m6A gene expression was established, highlighting five genes\u2014WTAP, METTL14, ZC3H13, PCIF1, and RBM15\u2014with significant effect coefficients. Unsupervised clustering of hub genes indicated that METTL14, HNRNPA2B1, YTHDF3, YTHDF2, YTHDC1, and YTHDC2 are potential discriminators in PCOS. The analysis of immune infiltration revealed a correlation between m6A regulators and immune cell levels, with METTL3 showing the most significant regulatory impact.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      <jats:italic>N<\/jats:italic>\n                      <jats:sup>6<\/jats:sup>\n                      \u2010methyladenosine RNA methylation regulators are intricately linked with the development of PCOS and may influence immune cell infiltration in affected individuals.
