Introduction: Loss of function mutations in SGPL1, a key component of sphingolipid metabolism, are associated with accumulation of sphingolipid intermediates giving rise to a multisystemic disease incorporating primary adrenal insufficiency (PAI) and progressive renal and neurological disease. Sphingolipid accumulation is implicated in mitochondrial pathology.Objective: To investigate the impact of SGPL1 deficiency on mitochondrial morphology/ f...

Triple A syndrome (AAAS) is a rare, incurable, homozygous disorder, characterised by tissue-specific degeneration resulting in adrenal failure and neurodisability. The AAAS gene encodes ALADIN, a nuclear pore complex (NPC) protein necessary for nuclear import of DNA protective molecules, important for redox homeostasis. ALADIN’s role is not fully characterised: its discovery at the centrosome and the endoplasmic reticulum suggests a role outside the NPC. The inte...
