CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): type (NPHS1) is an autosomal recessive disorder char-acterized by severe proteinuria of intrauterine onset. Diagnosis is by determination of urine protein/creatinine ratio in a random urine sample or measurement of urinary protein in a 24-hour urine collection; cause is diagnosed based on history . It has, however, been described in various ethnic groups throughout the world [3,4]. Congenital nephrotic syndrome (CNS) is a very rare form of nephrotic syndrome. Kidney biopsies show nonspecific histologic changes such as minimal change, focal segmental glomerulosclerosis (FSGS), and diffuse mesangial proliferation. Progression to end-stage kidney failure occurs during early childhood and the only curative treatment is kidney transplantation. Congenital nephrotic syndrome of the Finnish type is a familial nephrosis characterized by massive proteinuria, hypoalbuminemia, edema, and hyperlipidemia. Although it is named the Finnish type, it can occur outside Finland 3 . Fin-major and Fin-minor were the first two main genetic mutations identified in Finnish newborns, however, numerous mutations have now been identified in patients all over the world from various ethnic groups.

To elucidate whether other mutations of ACTN4 exist in PNS patients, we sequenced the ACTN4 . The condition is caused by a defect in the protein nephrin, which is found in the kidney. First described by Gautier and Miville in 1942, congenital nephrotic syndrome (CNS) is defined as the triad of nephrotic range proteinuria (>200mg/mmol creatinine), hypoalbuminaemia and clinically detectable edema, occurring in the first three months of life.
