Renal Slit Diaphragm – the Open Zipper and the Failing Heart

    Summary

    Inherited forms of proteinuria constitute a rare and heterogeneous group of diseases, the most prominent of which is glomerular dysfunction, which leads to proteinuria. Investigation of the genetic background underlying these diseases has provided significant data on the normal operation of the glomerular filter. Among the different components of the glomerulus, the podocyte slit diaphragm is considered the main source for genetically derived protein alteration, which leads in turn to proteinuria. Investigation of the different proteins revealed that the lack of nephrin and podocin is the leading cause of several inherited forms of proteinuria. It was also proposed that the lack of podocin is linked to cardiac anomalies. This review suggests that the absence of slit diaphragm proteins and the open zipper phenomenon are associated with cardiac anomalies.
