Congenital Nephrotic Syndrome - Finish Type

Area of Science:

• Pediatric Nephrology
• Medical Genetics

Background:

• The NPHS1 gene encodes nephrin, and its mutations are a primary cause of congenital nephrotic syndrome (CNS).
• While NPHS1 mutations are prevalent in Finnish CNS cases (98%), incidence varies globally (39-80%).

Observation:

• A two-week-old neonate presented with edema, abdominal distention, heavy proteinuria, hypoproteinemia, and failure to thrive.
• Clinical symptoms indicated a severe nephrotic presentation in the neonate.

Findings:

• Genetic analysis confirmed a mutation in the NPHS1 gene.
• The patient was diagnosed with congenital nephrotic syndrome, Finnish type.

Implications:

• This case underscores the diagnostic and therapeutic hurdles for rare congenital diseases in resource-limited settings.
• Raising awareness is crucial for improving management of congenital nephrotic syndrome in developing countries.
