Abstract
IgA nephropathy (IgAN) combined with myeloid bodies have been reported in Fabry disease (FD). However, we excluded the diagnosis of FD by no mutation in GLA gene. And she denied the use of cationic amphiphilic drugs. Interestingly, we identified a novel missense mutation for COQ2, which can cause COQ2 mutation associated nephropathy. The patient we reported also had heteromorphic mitochondria, and a good curative effect after CoQ10 supplementation. Combined these, this patient was diagnosed with COQ2 nephropathy and IgAN. To our knowledge, this is the first case report that COQ2 nephropathy with pathologic manifestations of myeloid body in podocytes.
