Abstract
Congenital nephrotic syndrome (CNS) is a rare disease
defined as heavy proteinuria, hypoalbuminemia, hyperlipidemia, and edema presenting in the first three months
of life. It is most commonly caused by mutations in the
NPHS1 gene associated with nephrotic syndrome type 1,
also known as Finnish-type CNS, which is inherited in an
autosomal recessive manner. Symptomatic treatment with
intravenous albumins, vitamins, minerals, nutritional, and
hormonal supplementation and treatment of complications are mandatory. Children refractory to the symptomatic treatment are recommended to undergo nephrectomy and renal replacement therapy, preferably renal
transplantation. We report on a child with Finnish type CNS
with a NPHS1 mutation, which is the first case confirmed
by genetic study in Slovenia. We showed for the first time
that homozygous mutation c.2928-3del in the NPHS1 gene
caused exon 22 skipping, leading to a truncated protein
and Fin-minor phenotype.
