Porphyria / p ɔːr ˈ f ɪr i ə / is a group of disorders in which substances called porphyrins build up in the body, adversely affecting the skin or nervous system. [1] The types that affect the nervous system are also known as acute porphyria , as symptoms are rapid in onset and short in duration. [ 1 ]
Paraphilias are sexual interests in objects, situations, or individuals that are atypical. The American Psychiatric Association, in its Diagnostic and Statistical Manual, Fifth Edition (DSM), draws a distinction between paraphilias (which it describes as atypical sexual interests) and paraphilic disorders (which additionally require the experience of distress, impairment in functioning, and/or ...
Porphyria cutanea tarda is the most common subtype of porphyria. [1] The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs.
In non-photosynthetic eukaryotes such as animals, insects, fungi, and protozoa, as well as the α-proteobacteria group of bacteria, the committed step for porphyrin biosynthesis is the formation of δ-aminolevulinic acid (δ-ALA, 5-ALA or dALA) by the reaction of the amino acid glycine with succinyl-CoA from the citric acid cycle.
Hepatic porphyrias is a form of porphyria in which toxic porphyrin molecules build up in the liver. Hepatic porphyrias can result from a number of different enzyme deficiencies. [1] Examples include (in order of synthesis pathway): [citation needed] Acute intermittent porphyria; Porphyria cutanea tarda and Hepatoerythropoietic porphyria
Variegate porphyria is inherited in an autosomal dominant pattern, which means the defective gene is located on an autosome, and inheriting one copy of the defective gene from an affected parent is sufficient to cause the disorder. More severe cases result from inheriting two copies of the defective gene.
