Methods for identifying subjects with a genetic risk for developing IgA nephropathy
Seven protective alleles for IgA nephropathy have been discovered that can be identified by analyzing a DNA sample for seven respective SNPs. A method is provided for identifying and treating subjects at risk of developing IgA neuropathy based on a new seven-SNP genetic risk score. Also provided are screening methods to identify compounds that bind to and reduce the expression or biological activity of a either CFHR1 or CFHR3.
1. A method for treating IgA nephropathy (IgAN) in a subject having IgAN by reducing the expression of CFHR1 or CFHR3, or both, comprising administering therapeutically effective amounts of inhibitory oligonucleotides that reduce the expression of CFHR1 or CFHR3, or both to the subject, wherein the inhibitory oligonucleotides comprise sufficient complementarity to the CFHR1 RNA or CFHR3 RNA to bind thereto under physiological conditions.
2. The method of claim 1 , wherein the inhibitory oligonucleotides are selected from the group consisting of siRNA, antisense, shRNA, microRNAs, microRNA mimetics, and ribozymes.
