inherited disorder characterized by mental retardation, decreased muscle tone, and life-threatening obesity including jerky movements and spontaneous laughter

3. What is the cause of genetic disorder "Canavan Disease"?

progressive damage to nerve cells in the brain

high pitched infant’s cry and sounds like a cat

5. What is the cause of genetic disorder "Celiac Disease"?

damage to the small intestine when certain types of protein, called gluten, are eaten

6. What is the cause of genetic disorder "Color Blindness"?

unable to see colors in a normal way

7. What is the cause of genetic disorder "Cystic Fibrosis"?

exocrine glands of afflicted individuals produce abnormally thick mucus that block the intestines and lung passageways

8. What is the cause of genetic disorder "DiGeorge Syndrome"?

congenital heart problems, frequent infections

9. What is the cause of genetic disorder "Down Syndrome"?

caused by trisomy of chromosome 21 resulting in physically and mentally retarded patient with widely separated eyes

10. What is the cause of genetic disorder "Fragile X"?

learning disabilities and cognitive impairment

11. What is the cause of genetic disorder "Glactosemia"?

causes the body to absorb too much iron from the diet

caused by recessive autosomal gene resulting into brain damage

18. What is the cause of genetic disorder "Polycystic Kidney Disease"?

growth of numerous cysts in the kidneys which reduce kidney function and lead to kidney failure

19. What is the cause of genetic disorder "Sickle Cell Anaemia"?

caused by recessive gene that lead to abnormal haemoglobin molecule and sickle shaped RBC with reduced haemoglobin

20. What is the cause of genetic disorder "Tay Sach Disease"?

caused by autosomal recessive gene resulting in cerebral degeneration and epilepsy

21. What is the cause of genetic disorder "Thalassemia"?

caused by recessive gene resulting in abnormality in haemoglobin structure

22. What is the cause of genetic disorder "Turner Syndrome"?

caused by lack of x-chromosome resulting in phenotypical female but rudimentary sex organs
