MIR31HG and IgA glomerulonephritis: Through a study including 413 Chinese IgAN patients and 423 healthy people, several single nucleotide polymorphisms (SNPs) in MIR31HG, such as rs1332184 and rs55683539, were significantly associated with an increased risk of IgA nephropathy, creatively indicating that individuals with MIR31HG overexpression were likely to be more susceptible to IgAN (Yuan et al., 2020).
