Hanhart Syndrome

There exist five types of Hanhart syndrome, with the severity and nature of the condition ranging widely on a case-by-case basis. Hanhart syndrome is classified as a rare disease, with only 30 known cases having been diagnosed between 1932 and 1991. Early hypotheses believed that the disease was caused by genetic conditions, with a more recent hypothesis demonstrating evidence that the disease may be caused by hemorrhagic lesions during prenatal development. The causal mechanism behind this vascular disruption is still unknown. Discovery and etymology Hanhart syndrome was first described in 1932 by Dr. Ernst Hanhart.
