Project description:Progressive familial intrahepatic cholestasis is caused by mutations in the ABCB4 gene and belongs to the family of familial intrahepatic cholestais disorders inherited in an autosomal recessive pattern. To date, about 200 patients with various hepatobiliary disorders associated with ABCB4 gene mutations have been described in the literature. The aim of this manuscript was to describe the pathogenesis, clinical presentation, diagnostic process and treatment of progressive familial intrahepatic cholestais type 3, based on the literature review.

Project description:Progressive familial intrahepatic cholestasis (PFIC) is a chronic cholestasis syndrome that begins in infancy and usually progresses to cirrhosis within the first decade of life. There are three varieties of PFIC described: PFIC-1 occurs due to mutations in the ATP8B1 gene mapped to 18q21.31, PFIC-2 due to mutations in ABCB11 mapped to 2q24, and PFIC-3 due to mutations in ABCB4 located on 7q21.12. We report an Indian child whose mutation analysis was suggestive of PFIC-2. He underwent a biliary diversion at 3½ years of age but subsequently died secondary to massive hematemesis.

Project description:Progressive familial intrahepatic cholestasis (PFIC) is a group of severe genetic disorders, inherited in an autosomal recessive manner, causing cholestasis of hepatocellular origin, later progressing to biliary cirrhosis and liver failure. This is the first report of PFIC type 1 with novel compound heterozygous mutations in Korea. The patient was presented with intrahepatic cholestasis, a normal level of serum γ-glutamyl transferase, steatorrhea, and growth failure. Genetic testing of this patient revealed novel compound heterozygous mutations (p.Glu585Ter and p.Leu749Pro) in the ATP8B1 gene. After a liver transplantation at age 19 months, the patient developed severe post-transplant steatohepatitis.

Project description:Progressive familial intrahepatic cholestasis (PFIC or Byler disease) is a rare autosomal recessive form of severe and fatal cholestatic liver disease. A locus for PFIC has recently been mapped to chromosome 18q21-q22 in the original Byler pedigree. This region harbours the locus for a related phenotype, benign recurrent intrahepatic cholestasis (BRIC), suggesting that these traits are allelic. Linkage analysis was undertaken in five consanguineous PFIC pedigrees from Saudi Arabia using marker loci (D18S69, D18S41, D18S64, D18S38, D18S42, D18S55, D18S68, and D18S61) which span the Byler disease/BRIC region on 18q21-q22. In this family set the disease locus was excluded from this region, showing that locus heterogeneity exists for the PFIC phenotype.

Project description:Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of disorders characterized by defects in bile secretion and presentation with intrahepatic cholestasis in infancy or childhood. The most common types include PFIC 1 (deficiency of FIC1 protein, ATP8B1 gene mutation), PFIC 2 (bile salt export pump deficiency, ABCB11 gene mutation), and PFIC 3 (multidrug resistance protein-3 deficiency, ABCB4 gene mutation). Mutational analysis of subjects with normal gamma-glutamyl transferase cholestasis of unknown etiology has led to the identification of newer variants of PFIC, known as PFIC 4, 5, and MYO5B related (sometimes known as PFIC 6). PFIC 4 is caused by the loss of function of tight junction protein 2 (TJP2) and PFIC 5 is due to NR1H4 mutation causing Farnesoid X receptor deficiency. MYO5B gene mutation causes microvillous inclusion disease (MVID) and is also associated with isolated cholestasis. Children with TJP2 related cholestasis (PFIC-4) have a variable spectrum of presentation. Some have a self-limiting disease, while others have progressive liver disease with an increased risk of hepatocellular carcinoma. Hence, frequent surveillance for hepatocellular carcinoma is recommended from infancy. PFIC-5 patients usually have rapidly progressive liver disease with early onset coagulopathy, high alpha-fetoprotein and ultimately require a liver transplant. Subjects with MYO5 B-related disease can present with isolated cholestasis or cholestasis with intractable diarrhea (MVID). These children are at risk of worsening cholestasis post intestinal transplant (IT) for MVID, hence combined intestinal and liver transplant or IT with biliary diversion is preferred. Immunohistochemistry can differentiate most of the variants of PFIC but confirmation requires genetic analysis.

Project description:Progressive familial intrahepatic cholestasis type 3 (PFIC3) is a rare monogenic disease caused by mutations in the ABCB4 gene, resulting in a reduction in biliary phosphatidylcholine. Reduced biliary phosphatidylcholine cannot counteract the detergent effects of bile salts, leading to cholestasis, cholangitis, cirrhosis and ultimately liver failure. Here, we report results from treating two- or five-week-old Abcb4-/- mice with an AAV vector expressing human ABCB4, resulting in significant decreases of PFIC3 disease biomarkers. All male mice achieved a sustained therapeutic effect up through 12 weeks, but the effect was achieved in only 50% of females. However, two-week-old females receiving a second inoculation three weeks later maintained the therapeutic effect. Upon sacrifice, markers of PFIC3 disease such as, hepatosplenomegaly, biliary phosphatidylcholine and liver histology were significantly improved. Thus, AAV-mediated gene therapy successfully prevented PFIC3 symptoms in a clinically relevant mouse model, representing a step forward in improving potential therapy options for PFIC3 patients.

Project description:Progressive familial intrahepatic cholestasis type I (PFIC1) is an autosomal recessive disorder caused by biallelic mutations of ATP8B1 gene, with progressive cholestasis as the main clinical manifestation. This paper reports the clinical and genetic features of a PFIC1 patient definitely diagnosed by ATP8B1 genetic analysis. The patient, a boy aged 14 months, was referred to the hospital with the complaint of jaundiced skin and sclera over 10 months. The patient had been managed in different hospitals, but the therapeutic effects were unsatisfactory due to undetermined etiology. On physical examination, hepatosplenomegaly was discovered in addition to jaundice of the skin and sclera. The liver was palpable 4 cm below the right subcostal margin and 2 cm below the xiphoid while the spleen 2 cm below the left subcostal margin. The liver function test revealed elevated levels of serum total bile acids, bilirubin, and transaminases; however, the γ-glutamyl transferase level was normal. The diagnosis was genetic cholestasis of undetermined origin. At the age of 1 year and 8 months, a Roux-en-Y cholecystocolonic bypass operation was performed, and thereafter the jaundice disappeared. At 5 years and 1 month, via whole genome sequencing analysis and Sanger sequencing confirmation, the boy was found to be a homozygote of mutation c.2081T>A(p.I694N) of ATP8B1 gene, and thus PFIC1 was definitely diagnosed. The boy was followed up until he was 6 years, and jaundice did not recur, but the long-term outcome remains to be observed.
