The WX and RW mutations in the porphobilinogen deaminase gene in acute intermittent porphyria have higher clinical penetrance than RW. Avoid drugs and chemicals known to exacerbate porphyria, particularly prescribed medication and over the counter medication. Total fecal porphyrin concentration or coproporphyrin isomer ratio is normal. Genetic Counseling Genetic counseling is the process of providing individuals and families with information on the nature, inheritance, and implications of genetic disorders to help them make informed medical and personal decisions.

If they are, they should follow the advice given above. Differences in perspective may exist among medical professionals and within families regarding the use of prenatal testing, particularly if the testing is being considered for the purpose of pregnancy termination rather than early diagnosis. Indications include repeated life-threatening acute attacks, failure of medical therapy, and poor quality of life [ Seth et al ]. Liver transplantation for acute intermittent porphyria is complicated by a high rate of hepatic artery thrombosis.

Attacks of acute porphyria may be precipitated by endogenous or exogenous factors [ Anderson et al ]. Knowledge about the safety of many drugs and other over-the-counter preparations in acute porphyrias is incomplete; however, evidence-based guidelines for assessment of drug porphyrogenicity have been published [ Thunell et alHift et al ].

This page was last edited on 16 Novemberat The following section deals with genetic risk assessment and the use of family history and genetic testing to clarify genetic status for family members. Data are compiled from the following standard references: The risk of provoking an acute attack may be highest ibtermittant women with acute intermittent porphyria, high urinary porphobilinogen PBG levels, or both of these together.

The color is enhanced by exposure to air and light and reflects increased urinary concentrations of porphyrins and porphobilins formed from the porphyrin precursor porphobilinogen PBG. Offspring of a proband.

Disorders of heme biosynthesis: AIP is inherited in an autosomal dominant manner. The diagnosis of AIP in a symptomatic individual is based on increased PBG in a random urine sample protected from light prior to analysistogether with evidence of a normal total fecal porphyrin or normal coproporphyrin isomer ratio, and plasma porphyrin fluorescence emission scan that is either normal or shows a peak emission around nm.

However, this advice is not always acceptable particularly to women who have never had symptoms, some of whom may already be taking the pill when they are found to have porphyria.
