- Progressive Familial Intrahepatic Cholestasis (PFIC) is an inherited disorder that causes liver damage in the form of cirrhosis and related symptoms due to the accumulation of bile in the liver. There are three types of PFIC that are caused by changes in different genes but have similar symptoms and presentation. Individuals with PFIC1 are more severely affected and have additional health concerns on top of liver disease. Individuals with PFIC2 and PFIC3 show symptoms that are primarily associated with liver disease only and vary in age of onset and severity. All three types of PFIC are inherited in an autosomal recessive manner.
- The Igenomix Progressive Familial Intrahepatic Cholestasis Precision Panel can be used to make a directed and accurate differential diagnosis of liver disease, ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes involved.
The Igenomix Progressive Familial Intrahepatic Cholestasis Precision Panel is indicated for those patients with a clinical suspicion or diagnosis of hemochromatosis presenting with the following manifestations:
- Itching (pruritus)
- Yellow skin (jaundice)
- Poor growth and weight gains
- Enlargement of the liver and spleen (hepatomegaly, splenomegaly)
The clinical utility of this panel is:
- The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient.
- Early initiation of treatment with a multidisciplinary team for early pharmacologic treatment, surgical care, and dietary modifications.
- Risk assessment of asymptomatic family members according to the mode of inheritance.
