Focal segmental glomerulosclerosis

Focal segmental glomerulosclerosis (FSGS) is a clinicopathological syndrome or diagnostic term for glomerular injury characterized by the partial scarring of glomeruli. Clinical features include proteinuria, reduced glomerular filtration rate and oedema. FSGS is an important cause of renal failure in adults and nephrotic syndrome in children.

    Okamoto et al. report that APOL1 RNA, but not protein, expressed from chronic kidney disease (CKD)-associated alleles activates protein kinase R, inducing glomerular injury in a mouse model. The secondary structure of APOL1 risk variant RNA acts as a scaffold for protein kinase R, suggesting potential therapeutic strategies for CKD.

    Martin Zenker, Corinne Antignac, Friedhelm Hildebrandt and colleagues report that mutations in OSGEP, TP53RK, TPRKB and LAGE3, genes encoding KEOPS-complex subunits, cause Galloway–Mowat syndrome, a recessive disease characterized by early-onset steroid-resistant nephrotic syndrome and microcephaly. Functional studies suggest that the phenotypes result from impaired protein translation, thus leading to endoplasmic reticulum stress and apoptosis.
