Outlines of Porphyrias

 



Introduction:

Porphyria is a group of rare genetic disorders that affect the production of heme, a vital component of hemoglobin in red blood cells. The condition results in a buildup of porphyrins, which are precursors to heme, and their byproducts in the body. This can cause a range of symptoms, including abdominal pain, skin sensitivity, and neurological problems. In this paper, we will discuss the types, causes, diagnosis, and treatment of porphyria.

Types:

There are several types of porphyria, including acute intermittent porphyria, congenital erythropoietic porphyria, hereditary coproporphyria, porphyria cutanea tarda, variegate porphyria, and ALAD porphyria. Each type has its own set of symptoms and specific genetic mutations that cause the condition.

Causes:

Porphyria is caused by mutations in genes that are involved in the production of heme. These mutations can be inherited from one or both parents, or they can occur spontaneously. Some triggers for porphyria attacks include certain medications, alcohol, fasting, hormonal changes, and exposure to sunlight.

Diagnosis:

Diagnosing porphyria can be challenging because the symptoms can mimic those of other conditions. Blood, urine, and stool tests can help identify the presence of porphyrins and their byproducts. Genetic testing can also be used to confirm a diagnosis and determine the specific type of porphyria.

Treatment:

Treatment for porphyria depends on the type and severity of the condition. Acute attacks may require hospitalization and treatment with intravenous heme or glucose. Other treatments may include avoiding triggers, taking medications to reduce symptoms, and receiving regular heme infusions to prevent further attacks. In some cases, liver transplantation may be necessary.

Conclusion:

Porphyria is a rare genetic disorder that can cause a range of symptoms and complications. Early diagnosis and appropriate treatment can help manage symptoms and prevent serious complications. Genetic testing can also be helpful in identifying family members who may be at risk for inheriting the condition. Ongoing research into the causes and treatment of porphyria is essential to improving outcomes for individuals with this condition.


Peutz-Jegher Syndrome PJS



- It's inherited in an Autosomal Dominant pattern

- Due to mutation in STK11 gene [ also known as LKB1 ] which is tumor suppressor gene. 

       →   its mutations disrupting its ability to restrain the cell division       
 

- Characterestic by development of non-cutaneous growths called hamartomatous polyps in the 

   gastrointestinal tract particulary stomach and intestine 

- The polyps have a great risk of develop cancer
