5. Swelling of the extremities
Turner’s syndrome can also lead to chronic swelling of the extremities. Some doctors have posed the possibility that the erroneous genetic area in the X chromosome leads to impaired immune function. If this theory proves true, it would mean that the immune system is mistaking healthy cells for invasive pathogens which leads to the swelling and sometimes inflammation of the extremities.
The confirmation of this theory would put turner syndrome into the autoimmune category of diseases. One of the risks that this runs is the fact that it will make it difficult for doctors to diagnose allergic reactions or anaphylaxis. Some patients with both a peanut allergy and turner syndrome died from anaphylaxis due to the fact that doctors were unable to differentiate between the symptoms of their allergic reaction and the chronic swelling caused by the syndrome.
