Presentation
Treatment-resistant nephrotic syndrome generally presents in the third month of life, but albuminuria may be present from birth 1. Etiology Five monogenic mutations have been implicated in the pathogenesis of Galloway-Mowat syndrome. [radiopaedia.org]
Case Presentation A 26-month-old boy presented to our hospital with periorbital edema and ascites. The patient was being followed up at another center for nystagmus and microcephaly. He was the only child of a nonconsanguineous healthy couple. [hindawi.com]
Continuous variables are presented as medians (ranges), and categorical variables are presented as percentages. [ncbi.nlm.nih.gov]
Case presentation We present the clinical and genetic characteristics of two unrelated infants with clinical suspicion of GAMOS who were born from consanguineous parents. [bmcnephrol.biomedcentral.com]

Workup
Clinical Testing and Workup In affected infants, symptoms associated with nephrotic syndrome may become apparent within days, weeks, months, or in some cases, years after birth. [rarediseases.org]
In consideration of the various renal manifestations of OSGEP mutations, patients should undergo a complete nephrological workup. [ncbi.nlm.nih.gov]

OR Surgery is not the first-line treatment option for patients with [disease name]. [wikidoc.org]
Treatment with corticosteroids and/or immunosuppressive drugs has not been effective for nephrotic syndrome associated with Galloway-Mowat syndrome. [rarediseases.org]

Prognosis
Overall, the long-term prognosis is not favourable, especially in early-onset cases, while the prognosis in late-onset cases, as in ours, is somewhat favourable. [scielo.mec.pt]
Treatment and prognosis There is no treatment for Galloway-Mowat syndrome 1. Affected individuals may survive for one year 1. References Promoted articles (advertising) [radiopaedia.org]
Conclusion: GAMOS3 is a progressive renal-neurological syndrome with a poor prognosis, especially with congenital NS. Microcephaly with dysmorphic features are vital clues to further evaluate renal impairment and brain anomalies. [pubmed.ncbi.nlm.nih.gov]
The prognosis for patients with GAMOS3 was poor, with a median survival of 8 months. Microcephaly (92%, 34/37) seems to be the more important clue for the timely diagnosis of GAMOS3 than early-onset NS. [ncbi.nlm.nih.gov]
OR Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%. [wikidoc.org]
Etiology
The etiology of GAMOS has a heterogeneous genetic contribution. Mutations in more than 10 different genes have been reported in GAMOS patients. [xenbase.org]
Etiology Five monogenic mutations have been implicated in the pathogenesis of Galloway-Mowat syndrome. WD repeat-containing protein 73 (WDR73), which is a critical scaffold component of protein-complex assembly, was the first to be identified 1,2. [radiopaedia.org]
However, the genetic etiology of more than three-quarters of patients with a clinical diagnosis of GAMOS remains elusive, suggesting that additional causative genes remain to be identified. [bmcnephrol.biomedcentral.com]
Epidemiology
Epidemiology and Demographics Galloway-Mowat syndrome affects males and females in equal numbers. More than 70 cases have been reported in the medical literature. [wikidoc.org]
Pathophysiology
OR The pathophysiology of [disease/malignancy] depends on the histological subtype. Causes In 2014, Galloway-Mowat syndrome was shown to be caused by alterations (mutations) in the WDR73 gene in a subset of cases. [wikidoc.org]
In 1994, Cohen and Turner examined kidney tissues of the patients using antibodies against glomerular basal membrane, tubular basal membrane, type IV collagen, and laminin along with different stains in an attempt to understand the pathophysiology of [hindawi.com]
Prevention
Other primary prevention strategies include [strategy 1], [strategy 2], and [strategy 3]. Secondary Prevention There are no established measures for the secondary prevention of [disease name]. [wikidoc.org]
Therapy with anti-seizure (anticonvulsant) drugs may be prescribed for affected individuals who experience seizures to help prevent, reduce, or control seizures. [rarediseases.org]
In our clinical experience, appropriate supportive care, including the maintenance of internal homeostasis, adequate nutrition and the prevention and treatment of infection (18), may temporarily alleviate clinical symptoms. [ncbi.nlm.nih.gov]
