Recent studies have highlighted a relationship between &lt;i&gt;VEGFA&lt;/i&gt; expression and renal cell carcinoma occurrence. However, the expression level, gene regulation network, prognostic value, and target prediction of &lt;i&gt;VEGFA&lt;/i&gt; in renal cell carcinoma remain unclear. Therefore, system analysis of the expression, gene regulation network, prognostic value, and target prediction of &lt;i&gt;VEGFA&lt;/i&gt; in patients with renal cell carcinoma is of great theoretical significance as there is a clinical demand for the discovery of new renal cell carcinoma treatment targets and strategies to further improve renal cell carcinoma treatment efficacy.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study used multiple free online databases, including cBioPortal, TRRUST, GeneMANIA, GEPIA, Metascape, UALCAN, LinkedOmics, Metascape, and TIMER for the abovementioned analysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;&lt;i&gt;VEGFA&lt;/i&gt; was upregulated in patients with kidney renal clear cell carcinoma (KIRC) and kidney chromophobe (KICH), and downregulated in patients with kidney renal papillary cell carcinoma (KIRP). Moreover, genetic alterations of &lt;i&gt;VEGFA&lt;/i&gt; were found in patients with renal cell carcinoma as follows: 4% (KIRC), 8% (KICH), and 4% (KIRP). The promoter methylation of &lt;i&gt;VEGFA&lt;/i&gt; was lower and higher in patients with clinical stages of KIRC and stage 1 KIRP, respectively. &lt;i&gt;VEGFA&lt;/i&gt; expression significantly correlated with KIRC and KIRP pathological stages. Furthermore, patients with KICH and KIRP having low &lt;i&gt;VEGFA&lt;/i&gt; expression levels had a longer survival than those having high &lt;i&gt;VEGFA&lt;/i&gt; expression levels. &lt;i&gt;VEGFA&lt;/i&gt; and its neighboring genes functioned in the regulation of protein methylation and glycosylation, as well as muscle fiber growth and differentiation in patients with renal cell carcinoma. Gene Ontology enrichment analysis revealed that the functions of &lt;i&gt;VEGFA&lt;/i&gt; and its neighboring genes in patients with renal cell carcinoma are mainly related to cell adhesion molecule binding, catalytic activity, acting on RNA, ATPase activity, actin filament binding, protease binding, transcription coactivator activity, cysteine-type peptidase activity, and calmodulin binding.
