Provided are methods of diagnosing IgA nephropathy in a subject. Optionally, the methods comprise isolating an IgG from the subject and determining whether the IgG binds to a galactose-deficient IgA1. Optionally, the methods comprise providing a biological sample from the subject and detecting in the sample a mutation in a IGH gene, wherein the mutation is in a nucleotide sequence encoding a complementarity determining region 3 (CDR3) of a IGH variable region. Optionally, the methods comprise determining a level of IgG specific for a galactose-deficient IgA1 in the subject.
