Familial steroid-resistant nephrotic syndrome with adrenal insufficiency

A rare disorder with multisystemic involvement and glomerulopathy characterized by progressive steroid-resistant nephrotic syndrome typically associated with focal segmental glomerulosclerosis, as well as primary adrenal insufficiency with adrenal calcifications. Age of onset and disease course are variable, with some cases presenting as severe fetal hydrops, while most patients present in infancy or early childhood and progress to end-stage renal disease within a few years. Additional features include ichthyosis, primary hypothyroidism, hypogonadism, immunodeficiency, and neurological manifestations (such as cognitive impairment, ataxia, sensorineural hearing loss, or seizures).
