Genetic disorders


Hello bio class!

Today I will explain the basics of Patau's syndrome, or Trisomy13. Trisomy 13 is a more specific explanation of the disorder. It literally is a third copy of the 13th chromosome in the human genome. This can cause overlapping of eyes, hands and other body parts, and other defects, and overall missing characteristics of the human structure. Most signs are visable at birth, such as the preceding symptoms, and various heart problems. The treatment depends on the symptoms. When the parents don't have the disease, the odds of a kid having it if their parents don't are about 1 in ten thousand. On average the life expectancy is less then a year, but again, it depends on the symptoms.
