PTPRO Possesses tyrosine phosphatase activity. Plays a role in regulating the glomerular pressure/filtration rate relationship through an effect on podocyte structure and function. Defects in PTPRO are the cause of nephrotic syndrome type 6 (NPHS6). NPHS6 is a renal disease characterized clinically by proteinuria, hypoalbuminemia, hyperlipidemia and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. Some affected individuals have an inherited steroid-resistant form and progress to end-stage renal failure. Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily. 4 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
