Congenital nephrotic syndromeInfant who develop nephrotic syndrome within the first 3 months of life are considered to have congenital nephrotic syndrome. The most common cause of this syndrome is finnish-type congenital nephrotic syndrome, an autosomal recessive disorder. Two most common genes involved are - i) NPHS1    -->  Coding for nephrin and results in finnish-type nephrotic syndrome.ii) NPHS2 --> Coding for Podocin and results in FSGS. Other important genes involved in steroid - resistant nephrotic syndrome
