Autonomic bladder dysfunction with impaired pupillary reflex and secondary CAKUT (congenital anomalies of the kidney and urinary tract) is an autosomal recessive neurogenic disorder with onset in utero or early childhood. Affected individuals have impaired neuronal bladder and ureteral innervation causing coordination defects that result in secondary structural defects of the renal system, including hydronephrosis, vesicoureteral reflux (VUR), and small kidneys, that may result in chronic kidney disease as well as recurrent urinary tract infections (UTIs). Surgical treatment of VUR is not effective. Most individuals also have additional autonomic features, most commonly impaired pupillary reflex and sometimes orthostatic hypotension (summary by Mann et al., 2019).

- Disease or Syndrome
Neurooculorenal syndrome (NORS) is an autosomal recessive developmental disorder with highly variable clinical manifestations involving several organ systems. Some affected individuals present in utero with renal agenesis and structural brain abnormalities incompatible with life, whereas others present in infancy with a neurodevelopmental disorder characterized by global developmental delay and dysmorphic facial features that may be associated with congenital anomalies of the kidney and urinary tract (CAKUT). Additional more variable features may include ocular anomalies, most commonly strabismus, congenital heart defects, and pituitary hormone deficiency. Brain imaging usually shows structural midline defects, including dysgenesis of the corpus callosum and hindbrain. There is variation in the severity, manifestations, and expressivity of the phenotype, even within families (Rasmussen et al., 2018; Munch et al., 2022).
