Genes affected
UMOD (HGNC:12559): (uromodulin) The protein encoded by this gene is the most abundant protein in mammalian urine under physiological conditions. Its excretion in urine follows proteolytic cleavage of the ectodomain of its glycosyl phosphatidylinosital-anchored counterpart that is situated on the luminal cell surface of the loop of Henle. This protein may act as a constitutive inhibitor of calcium crystallization in renal fluids. Excretion of this protein in urine may provide defense against urinary tract infections caused by uropathogenic bacteria. Defects in this gene are associated with the renal disorders medullary cystic kidney disease-2 (MCKD2), glomerulocystic kidney disease with hyperuricemia and isosthenuria (GCKDHI), and familial juvenile hyperuricemic nephropathy (FJHN). Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2013]

Pathogenic, criteria provided, single submitter | clinical testing | Victorian Clinical Genetics Services, Murdoch Childrens Research Institute | Jun 29, 2018 | A heterozygous inframe deletion-insertion variant, NM_003361.3(UMOD):c.278_289delinsCCGCCTCCT, has been identified in exon 3 of 11 of the UMOD gene. The variant is predicted to result in an inframe deletion-insertion at position 93 to 97 of the protein (NP_003352.2(UMOD):p.(Val93_Gly97delinsAlaAlaSerCys)). The variant is absent in population databases (gnomAD, dbSNP, 1000G). The variant has been previously described as pathogenic in many patients with either medullary cystic kidney disease type 2 (MCKD2) or UMOD-associated kidney disease (UMAK) (Wolf, M.T.F. et al., 2013, Smith, G.D. et al., 2011, Stewart, A.P. et al., 2015, Kim, Y. et al., 2017). Segregation has been reported with MCKD2 in one family and in four families with UMAK (Wolf, M.T.F. et al., 2013, Smith, G.D. et al., 2011). Protien modelling predictions of this variant demonstrated a loss of disulfide bridging resuting in unfolding of the N-terminal region (Smith, G.D. et al., 2011). Furthermore, in vitro and in vivo studies of this variant demostrated trafficking defects, endoplasmic reticulum retention, and a reduction in the amount of protein secretion (Stewart, A.P. et al., 2015). Based on the information available at the time of curation, this variant has been classified as PATHOGENIC. - |

Autosomal dominant medullary cystic kidney disease with or without hyperuricemia Pathogenic:2
Likely pathogenic, no assertion criteria provided | clinical testing | Sydney Genome Diagnostics, Children's Hospital Westmead | Sep 05, 2018 | This patient is heterozygous for the variant, c.278_289delinsCCGCCTCCT (p.Val93_Gly97delinsAlaAlaSerCys), in the UMOD gene. This variant, located in a calcium binding EGF domain of UMOD, is likely to be pathogenic as it results in the loss of 5 residues (ValCysProGluGly), including a conserved cysteine at position 94, and the insertion of 4 residues (AlaAlaSerCys). This variant has been previously reported in several members of a family with medullary cystic kidney disease (Wolf et al 2003 Kidney Int 64:1580-1587). This variant is referred to as 383del12/ins9 in this paper. - |
Pathogenic, criteria provided, single submitter | clinical testing | Molecular Genetics, Royal Melbourne Hospital | Nov 05, 2023 | This complex sequence change is a deletion of 12 bp and insertion of nine bp, predicted to cause a change in the length of the protein due to an in-frame substitution of five amino acids for four amino acids in a non-repeat region of the UMOD protein, p.(Val93_Gly97delinsAlaAlaSerCys). The variant alters a cysteine residue involved in a disulphide bond in the EGF-like domain 2 (PMID: 35273390, 36038257). This variant is absent from the population database gnomAD v2.1 and v3.1. It has been reported as a British founder variant for hereditary nephropathy and segregates with renal disease in multiple families (PMID: 36038257). The variant demonstrates deficient intracellular trafficking associated with endoplasmic reticulum retention and reduced secretion in multiple in vitro functional assays with limited validation (PMID: 22034507, 32954071). Based on the classification scheme RMH Modified ACMG Guidelines v1.6.1, this variant is classified as PATHOGENIC. Following criteria are met: PS4, PP1S, PM1, PM2P, PS3P. - |
