Gene: WDR73

WDR73 is associated with Galloway-Mowat syndrome 1 (251300) in OMIM.
Following discussion with some members of the GMS Renal Specialist Test group on 2019-03-22 it was agreed that proteinuria is a relevant feature of Galloway-Mowat syndrome, and WDR73 should be included on the Proteinuric renal disease panel.
PMID: 26123727 - Vodopiutz et al 2015. Report 2 patients from unrelated consanguineous families diagnosed with Galloway-Mowat syndrome. One with Indian one with Turkish ethnicity. Two variants identified, one missense, the other truncating; c.287G>A p.(Arg96Lys) and c.940C>T p.(Gln314*).
PMID: 25466283 - Colin et al 2014. Report 2 families with children with Galloway-Mowat syndrome. In family A (Moroccan) there are two affected children. One developed proteinuria, the other did not (at age 7). A homozygous A nonsense WDR73 mutation (c.129T>G [p.Tyr43∗]) was identified. In family B (consanguineous Turkish family) with one affected child who showed proteinuria as part of the phenotype, they detected another homozygous frameshift mutation in WDR73 (c.766dupC [p.Arg256Profs∗18]). Both variants segregated with the disease in the families, and neither is referenced in the NHLBI Exome Variant Server or in dbSNP.
PMID: 25873735 - Ben-Omran et al. (2015) - In 2 sisters, born of consanguineous Arab parents, with GAMOS1, identified a homozygous truncating mutation in the WDR73 gene (Q235X). One sister had proteinuria and other findings are suggestive of nephrotic disease (age 11 years), and the other sister at age 5 had findings suggestive of early features that might progress towards nephrotic disease.
PMID: 26070982 - Jinks et al. (2015) - report 27 Amish patients with GAMOS1 and identified a homozygous truncating mutation in the WDR73 gene. 57% developed steroid non-responsive, fluctuating proteinuria.Created: 26 Mar 2019, 12:51 p.m.
