Congenital nephrotic syndrome: Defined as nephrotic syndrome manifesting at bih or within 1st 3 months of life The Finnish type of congenital nephrotic syndrome is caused by autosomal recessive mutations in NPHS1 or NPHS2 gene, which encodes nephrin and podocin, critical components of the slit diaphragm Affected infants most commonly present at bih with edema caused by massive proteinuria.
