Kálmán Tory, Corinne Antignac and colleagues report that a variant of NPHS2, encoding p.Arg229Gln, causes nephrotic syndrome only when present in trans with particular mutations in the 3′ coding region of NPHS2. Mechanistically, the authors show that these 3′ mutations behave as recessive alleles when present with wild-type NPHS2 but exert a dominant-negative effect on the p.Arg229Gln variant, resulting in protein mislocalization.
