Podocyte injury and depletion significantly contribute to the pathogenesis and progression of FSGS. MicroRNAs (miRNAs) are noncoding RNAs that regulate the expression of specific genes in relevant cells, thereby playing crucial roles in the pathogenesis of FSGS. Many studies have shown that miRNAs can be secreted from cells into body fluids and that these miRNAs in the circulation are highly stable. The gold standard for FSGS diagnosis is kidney biopsy; however, the clinical heterogeneity of FSGS, along with variations in histology and nonspecific morphological features, can impact its diagnostic accuracy.
