Claims

exact text as granted — not AI-modified
1 - 21 . (canceled) 
     
     
         22 . A method of treating a renal disorder in a mammal, the method comprising the step of administering to the mammal an effective amount of a BCMA (B-Cell Maturation Antigen) polypeptide, wherein the BCMA polypeptide comprises an amino acid sequence that binds to BAFF (B-Cell Activating Factor of the TNF family; SEQ ID NO:9) and is:
 a) at least 95% identical to amino acids 1-51 of SEQ ID NO:1; or   b) at least 95% identical to amino acids 8-41 of SEQ ID NO:1.   
     
     
         23 . The method of  claim 22 , wherein the BCMA polypeptide comprises an Fc domain of an immunoglobulin. 
     
     
         24 . The method of  claim 22 , wherein the mammal is human. 
     
     
         25 . The method of  claim 22 , wherein the BCMA polypeptide comprises the sequence of amino acids 1-51 of SEQ ID NO:1. 
     
     
         26 . The method of  claim 22 , wherein the BCMA polypeptide comprises the sequence of amino acids 8-41 of SEQ ID NO:1. 
     
     
         27 . The method of  claim 23 , wherein the immunoglobulin is IgG. 
     
     
         28 . The method of  claim 23 , wherein the immunoglobulin is human.
