👉 Reticuloendotheliosis is a rare, genetic disorder characterized by an abnormal growth pattern in the brain and spinal cord that can lead to severe neurological issues and death if left untreated. It primarily affects individuals with a mutation in the PAX7 gene, which is involved in neuroectodermal development. This condition usually starts before birth or during pregnancy and is often diagnosed at birth due to symptoms like seizures, difficulty breathing, or increased sensitivity to light.
