A young child with pseudohypoaldosteronism type II by a mutation of Cullin 3

Background Pseudohypoaldosteronism type II (PHA II), also referred to as Gordon syndrome, is a rare renal tubular disease that is inherited in an autosomal manner. Though mutations in WNK1 and WNK4 partially account for this disorder, in 2012, 2 research groups showed that KLHL3 and CUL3 were the causative genes for PHA II. Here, we firstly report on the Japanese child of PHA II caused by a mutation of CUL 3.
