Finnish congenital nephrotic syndrome

The nephrotic syndrome is characterized clinically by proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Kidney biopsies show nonspecific histologic changes such as minimal change, focal segmental glomerulosclerosis (FSGS), and diffuse mesangial proliferation. Approximately 20% of affected individuals have an inherited steroid-resistant form and progress to end-stage renal failure (summary by Fuchshuber et al., 1996). Nephrotic syndrome type 1 (NPHS1) is characterized by prenatal onset of massive proteinuria followed by severe steroid-resistant nephrotic syndrome apparent at birth with rapid progression to end-stage renal failure (Kestila et al., 1998). Because of confusion in the literature regarding use of the terms 'nephrotic syndrome' and 'focal segmental glomerulosclerosis' (see NOMENCLATURE section), these disorders in OMIM are classified as NPHS or FSGS according to how they were first designated in the literature. Genetic Heterogeneity of Nephrotic Syndrome and Focal Segmental Glomerulosclerosis Nephrotic syndrome and FSGS are genetically heterogeneous disorders representing a spectrum of hereditary renal diseases.

FSGS4 (612551) has been mapped to chromosome 22q12, and FSGS5 (613237) is caused by mutation in the INF2 gene (610982). [from OMIM]

NEPHROTIC SYNDROME 15

NPHS15 is an autosomal recessive renal disorder characterized by onset of impaired kidney function with proteinuria in the first months of life. The disease course and severity varies widely. Some patients show rapid progression to end-stage renal failure necessitating transplant, whereas others have a more benign course that can be managed with medication. Renal biopsy tends to show glomerular sclerosis and effacement of podocyte foot processes (summary by Bierzynska et al., 2017). For a discussion of genetic heterogeneity of nephrotic syndrome and FSGS, see NPHS1 (256300). [from OMIM]
