Differentially altered expression of transcripts of retinoic acid receptors α, β, γ (Rarα, β, γ), which mediate the actions of all-trans retinoic acid (RA), is observed in glomeruli of nephrotic syndrome (NS) patients vs normal individuals, with Rarβ reduced and both RARα and RARγ increased. The gene discussed is RARA; the disease is Netherton syndrome.
