👉 Megalopsia is a rare genetic disorder that affects the development of the internal organs and tissues. It occurs due to a defect in the development of the neural tube, which is responsible for the formation of the brain and spinal cord. Megalopsia can cause a wide range of symptoms, including reduced growth, difficulty breathing, and changes in behavior and speech. Diagnosis is often made through genetic testing, and treatment options include surgery to correct the neural tube defects.
