%X Mesangial proliferative glomerulonephritis (MsPGN) is the most common clinicopathologic feature of the primary glomerulonephritis. The hereditary susceptibility to MsPGN is rather complex. In this report, a Chinese case of proliferative glomerulosclerosis was recruited. Renal biopsy revealed extensive glomerulosclerosis with mesangial hypertrophy, and tubular atrophy and dilatation. Whole exome sequencing (WES) revealed compound heterozygous variants in TTC21B gene, which were confirmed by Sanger sequencing. The variants in TTC21B gene were the molecular pathogenic basis of this disorder, and this case help to understand the correlation of genotype and phenotypes of TTC21B mutations.
