membranoproliferative glomerulonephritis

And we may find that when we do these trials of therapies, that we are actually identifying those subsets within this bigger lump of diseases.

Yeah, almost like MPGN all over again, we found out it's actually so many different diseases that we were just kind of lumping together.

Yeah, and I think that's likely going to be the case here, especially given the kind of quite wide phenotypic range of diseases that we all group together as APOL1 disease.

when we review genetic testings for children with APOL1 disease, is there a specific genotype that makes them a higher risk for a particular presentation? I know you had mentioned there's a wide variety in your phenotypic presentation, but for example, homozygous G1 or G2 or a mix that may have sort of like a higher predisposition for worse disease,
