A Study of Markers in the Blood and/or Stored Kidney Biopsy Tissue in Patients with a History of Childhood Onset of Membranous Nephropathy

Overview

About this study

The study is being done to look for markers in the blood and/or stored kidney biopsy tissue, in patients with a history of childhood onset Membranous Nephropathy. By collecting health information and laboratory samples, our goal is to learn more about membranous nephropathy.

Due to discovery of additional antibodies and antigens (Thrombospondin Type-1 Domain 7A, Semaphorin 3B, Exotosin-1 & 2, Neural epidermal growth factor-like type 1, Protocadherin 7 PCDH7, Protocadherin FAT1, and serine protease HTRA1) in children with MN over the last decade, we would like to expand serological and hisotological testing of these antibodies and antigens in the existing and archived samples to ensure a comprehensive investigation of this disease in the current study.
