2Causes of Mermaid Syndrome
The exact causes of mermaid syndrome are still unknown. However, many scientists believe that it may be attributed to a combination of certain genetic and environmental factors. Previous studies have found a link between differences in a genetic component called VANGL1 and a higher risk of developing mermaid syndrome. Nevertheless, it is still unclear why a genetic mutation may lead to this disorder. In addition, several environmental factors may be linked to mermaid syndrome. These include excessive use of alcohol during pregnancy, an imbalance of amino acid levels, exposure to retinoic acid, a deficiency of oxygen in the uterus, as well as exposure to harmful substances in cocaine, lithium, or tobacco products. Some cases of mermaid syndrome can be sporadic, which means that they happen for no known cause. They tend to result in reduced blood flow to the embryo, particularly in the area where the lower limbs of the babies may typically develop. [2]
