2. Hemophilia is a rare genetic blood disorder, in which one of the clotting factors in the blood is not produced. Queen Victoria of England, a famous carrier of the hemophilia gene. People with hemophilia may bleed for a longer time than others after an injury. They also may bleed internally, especially in the knees, ankles, and elbows.

6. abnormally thick mucus Cystic fibrosis (CF) is an inherited disease in which the body produces abnormally thick mucus in the lungs and pancreas. The mucus builds up in the lungs and blocks the airways. This makes it easy for bacteria to grow and leads to repeated serious lung infections. Over time, these infections can cause serious damage to the lungs. The thick, sticky mucus can also block tubes, or ducts, in the pancreas. As a result, digestive enzymes that are produced by the pancreas cannot reach the small intestine. These enzymes help break down the food that you eat. Without them, the intestines cannot absorb fats and proteins fully. Cystic Fibrosis Cystic Fibrosis

8. Turner Syndrome Syndrome Klinefelter Syndrome Triple X syndrome syndrome XYYXYY syndrome Genetic abnormalities of the XY Chromosomes

9. Fragile X syndrome is caused by a mutation in the FMR1 gene, located on the X chromosome. The mutated gene cannot produce enough of a protein that is needed by the body's cells, especially brain cells, to develop and function normally. There are a variety of symptoms, including: mental retardation, hyperactivity, short attention span, and autism. Click here to learn more about FXShere Fragile X Syndrome (FXS)
