Forensic scientists are able to use ink chromatography to solve crimes by matching documents or stains found at a crime scene to the marker or pen that belongs to a suspect. Forensic scientists analyze the unknown ink and compare it to writing utensils collected from possible suspects.
Symptoms of Variegate Porphyria The hepatic porphyrias primarily affect the nervous system, resulting in abdominal pain, vomiting, acute neuropathy, seizures, and mental disturbances, including hallucinations, depression, anxiety, and paranoia.
The skin lesions caused by variegate porphyria are identical to those in porphyria cutanea tarda, which is the most common of all the porphyrias. This disease does not cause neurological symptoms. It is caused by a deficiency of the uroporphyrinogen decarboxylase (UROD), the fifth enzyme in the heme pathway, in the liver.
