Summary
Galloway-Mowat syndrome, a rare genetic disorder, presents with early-onset nephrotic syndrome and CNS anomalies. This case highlights serial renal histopathology and ovarian agenesis, offering new insights into disease progression.
Area of Science:
- Genetics
- Nephrology
- Neurology
Background:
- Galloway-Mowat syndrome is characterized by early-onset nephrotic syndrome and central nervous system anomalies.
- Renal histopathology in Galloway-Mowat syndrome is variable, with unclear implications for disease progression.
- Associated anomalies like hiatal hernias are reported but not universal.
Observation:
- A patient with Galloway-Mowat syndrome underwent serial renal biopsies.
- Initial biopsy at 9 months showed minimal changes.
- Autopsy at 42 months revealed diffuse mesangial sclerosis, cerebral dysplasia, leukomalacia, cerebellar abnormalities, and bilateral ovarian agenesis.
Findings:
- This report details the first observation of serial histopathologic changes in the kidneys of a Galloway-Mowat syndrome patient.
- The study documents bilateral ovarian agenesis as a previously unreported feature of the syndrome.
- Neuropathologic findings included significant brain abnormalities.
Implications:
- The findings suggest that observed renal changes may represent different stages of Galloway-Mowat syndrome progression.
- Ovarian agenesis may be an under-recognized feature of Galloway-Mowat syndrome.
- This case expands the understanding of the phenotypic spectrum and natural history of Galloway-Mowat syndrome.
