Patau Syndrome, also known as Trisomy 13, is a genetic disorder caused by the presence of an extra copy of chromosome 13 or the improper placement of chromosome 13. It results in severe physical and mental abnormalities such as heart defects, unusual facial features, small head size, missing or small eyes, extra fingers and toes, and spinal defects. Diagnosis is typically made through ultrasounds, x-rays, MRI, CT scans, or chromosome studies. Treatments focus on addressing specific physical problems, though many infants have difficulties surviving beyond the first few weeks due to neurological or heart issues.
