Disease name : Progressive familial intrahepatic cholestasis ( PFIC )
Affected universe : PFIC is a grouping of rare genetic disease that causeprogressive liver nonstarter . The exact prevalence of PFIC is unknown , but estimates suggest that these disease affectbetween 1 in 100,000 and 1 in 50,000 peopleworldwide . In the United States , fewer than 50,000 peopletotal are believed to have PFIC .
PFIC is a group of rare genetic diseases that cause a digestive fluid called bile to accumulate in the liver (pictured in orange above), resulting in extensive damage that often necessitates a transplant.
Causes : Patients with PFIC have inherited mutations that impair theliver ’s ability tosecrete a digestive fluid known as bile into the digestive tract .
Bileis a yellowish - greenish fluid produced in the liver , and it is commonly secreted into the digestive piece of ground to help with the partitioning of blubber , the absorption of vitamin from food for thought , and the removal of waste material production in faecal matter .
But in patient with PFIC , gall instead accumulates in the liver and thus begins to damage the organ . As liver cells die , they are replaced with scar tissue paper , a process lie with as fibrosis .
PFIC causes severe scarring of the liver, known as cirrhosis.

There are three type of PFIC — PFIC1 , PFIC2 and PFIC3 — which differ in that they are triggered by mutations in dissimilar cistron that code for proteinsneeded for the liver to function properly . PFIC is inherit in anautosomal recessionary manner , signify that kid must inherit two copies of a relevant mutated gene — one from each parent — to develop the disease .
Symptoms : All patient with PFIC developsymptoms of liver disease , which typically come out during infancy . These symptoms include wicked itching ; a yellowing of the skin and whites of the centre , know asjaundice ; stunted growth ; and highblood pressurein the vein that carries blood from the digestive organization to the liver . The itchiness stems from excess bile acidirritating spunk cells in the body .
Patients with PFIC1 also may have other symptoms , such asshort stature , deafness , diarrhea and inflaming of the pancreas . And those with PFIC2 are at an increased peril of developing a type of liver cancer calledhepatocellular carcinoma .
symptom of liver failure usually develop before maturity in patient with PFIC1 . The prognosis is typically worse for affected role with PFIC2 whose livers fail within the first few years of spirit . patient with PFIC3 , on the other mitt , may grow liver-colored failure in puerility or adulthood .

intervention : There isno cure for PFIC , but steps can be lead to relieve patient ' symptom . For illustration , certain drugscanincrease the stream of gall out of the liver , while dietary supplement can invoke low levels ofvitamins and fatsin the blood because of the lack of bile secretion .
Even with these handling , though , most patients with PFIC willultimately demand a liver graft . This replaces damaged liver tissue withhealthy cells that do not have the familial defect , thus lift many symptoms of liver disease .
If leave untreated , PFIC killsan estimated 87 % of affected role . By comparison , several study have render that survival rates after liver transplantation rangebetween 76 % and 85 % ; one of these studies espouse patients for 19 years after the procedure .
