Although the exact cause of IgA nephropathy is unknown, these factors may increase your risk of developing this condition:

  • Your sex. In North America and western Europe, IgA nephropathy affects at least twice as many men as it does women.
  • Ethnicity. IgA nephropathy is more common in Caucasians and Asians than it is in blacks.
  • Family history. In some cases, IgA nephropathy appears to run in families, indicating that genetic factors may contribute to the disease.
