The three overlapping clinical uromodulin-associated kidney diseases (UAKD) are medullary cystic disease type 2, familial juvenile hyperuricemic nephropathy and glomerulocystic kidney disease.
Mutations of the UMOD gene, encoding uromodulin, have been associated with medullary cystic kidney disease 2, familial juvenile hyperuricemic nephropathy, and glomerulocystic kidney disease.
Uromodulin (UMOD) mutations were described in patients with medullary cystic kidney disease (MCKD2), familial juvenile hyperuricemic nephropathy (FJHN), and glomerulocystic kidney disease (GCKD).
Furthermore, the genetic basis of familial juvenile hyperuricemic nephropathy (FJHN), glomerulocystic kidney disease (GCKD) and autosomal dominant medullary cystic kidney disease 2 (MCKD2) has been recently attributed to mutations within the THP gene.
Autosomal dominant medullary cystic kidney disease type 2 (MCKD2), familial juvenile hyperuricemic nephropathy (FJHN), and autosomal dominant glomerulocystic kidney disease (GCKD) constitute a hereditary renal disease group that may lead to end-stage renal failure caused by mutations of the UMOD gene and its product, uromodulin or Tamm-Horsfall protein.
Immunohistochemistry on GCKD and MCKD/FJHN kidney biopsies revealed dense intracellular accumulation of uromodulin in tubular epithelia of the thick ascending limb of Henle's loop.
A novel mutation of the HNF1B gene associated with hypoplastic glomerulocystic kidney disease and neonatal renal failure: a case report and mutation update.
Immunohistochemistry on GCKD and MCKD/FJHN kidney biopsies revealed dense intracellular accumulation of uromodulin in tubular epithelia of the thick ascending limb of Henle's loop.
Mutations in the homeobox gene vHnf1 are associated with human diseases MODY5 (maturity-onset diabetes of the young, type V) and familial GCKD (glomerulocystic kidney disease).
Next-generation sequencing was used to evaluate for mutations in COL4A3 and COL4A4, associated with TBMN, and UMOD, MUC1, and SEC61A1, associated with hereditary GCKD.

Therefore, THGP modulation of ROMK function confers a new role of THGP on renal ion transport and may contribute to salt wasting observed in FJHN/MCKD-2/GCKD patients.
Furthermore, the genetic basis of familial juvenile hyperuricemic nephropathy (FJHN), glomerulocystic kidney disease (GCKD) and autosomal dominant medullary cystic kidney disease 2 (MCKD2) has been recently attributed to mutations within the THP gene.
A set of directed linkage strategies indicates that the distinctive GCKD phenotype in this family results from a dominantly acting mutation that disrupts a genetic locus distinct from the ADPKD loci, PKD1 and PKD2, as well the human homologue of mouse jcpk mutation, a newly described murine GCKD.
