it can be, if the porphyria is ACQUIRED, rather than inherited.
Missence mutation
You can have a baby with physical/mental deformities or death of the child.
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
A heritable character or genetic character
Porphyria is a metabolic disorder and is genetic. It is one of the acute porphyrias and cutaneous porphyria are also found within this condition. The gene mutation R59W carried within my family; the common defect responsible for Variegate Porphyria in South Africa, results in a faulty enzyme (protoporphyrinogen oxidase PPOX) that cannot handle the normal metabolism of porphyrins, which results in overproduction in the blood and urine.
First of all you must have a family history with porphyria; secondly the type of porphyria in your family must be definitely established as well as the mutation in your family. The porphyrias are a group of diseases (disorders) caused by the over-production of porphyrins, as a result of an inherited metabolic defect. In most cases the defect is genetic, except with one form porphyria cutanea tarda, that is however usually not genetic, but is acquired as a result of certain forms of liver dysfunction.A patient with porphyria have two major symptoms;the acute attack ( severe abdominal pain, nausea, vomiting, constipation, and pain in the back and limbs);and photosensitivity (due to sun-exposed areas, a skin disease develops with blisters and sores, particularly on the face and backs of the hands, forming scars, and healing takes longer than normal.Testing is very problematic and depends on the nature of your symptoms that you experience as well as in what country you live.It must be tested at a PORPHYRIA LABORATORY who are able to perform the complete range of tests necessary as incomplete results may be misleading in giving false-negative results. You have to submit a urine sample and a blood sample at a reputable porphyria laboratory for the following tests;Urine ALA and PBG measurement (this helps to exclude acute intermittent porphyria, and variegate porphyria in the acute attack).Urine porphyrin screening, followed by chromatographic quantitation if positive, to estimate the activity of acute intermittent porphyria and variegate porphyria, and to confirm porphyria cutanea tarda.Plasma fluorescence scan (this helps to exclude several porphyrias, including variegate porphyria and porphyria cutanea tarda).Erythrocyte fluorescence (this helps to exclude erythropoietic protoporphyria and congenital erythropoietic porphyria).DNA testing for the R59W mutation. (this is VP - Variegate Porphyria - South African mutation)If your results are negative, then your symptoms are not due to porphyria, and it is therefore highly unlikely that you in fact have porphyria. Your doctor must in any event help you to find another cause for your symptoms. (Source: Porphyria UCT SA)
Missence mutation
Swedish porphyria, pyrroloporphyria, and intermittent acute porphyria.
mutation
You can have a baby with physical/mental deformities or death of the child.
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
Deviation can destroy cell, causing death/mutation.
both depending on the type of porphyria
Porphyria's Lover was created in 1836.
mutation
The offspring of the organism will have a mutation.
