Since this disease is chromosomal, explain the abnormality.

Turner Syndrome is a chromosomal disease that has an abnormality in the X chromosomes. Girls can either have just one X instead of two or they can have two X's with one that is genetically altered. When there is just one X instead of two, the abnormality is the missing X. On the other hand when there is one whole X and another X that is altered there are three ways for it to be abnormal. The second X could have parts that have been deleted, broken, or duplicated. All these things cause the abnormality for Turner Syndrome.
