There were no pathogenic mutations of UMOD, MUC1, or SEC61A1, encoding uromodulin, mucin1, or Sec61 translocon alpha 1 subunit, which are causative proteins of autosomal dominant tubulointerstitial kidney disease, including GCKD. The gene discussed is UMOD; the disease is autosomal dominant medullary cystic kidney disease with or without hyperuricemia.
