چکیده

Background and Aim: Progressive familial intrahepatic cholestasis (PFIC) refers to a heterogeneous group of liver disorders childhood which have hepatocellular origin. Largely, there are three distinct forms PFIC- 1,2 3 due increased access genetic studies, this list has expanded with newer mutations genes being discovered each day. Our study aims contribute the sparse existing literature variations seen in PFIC patients from India. Methods: It is descriptive analyze clinical characteristics, disease severity who underwent targeted gene sequencing (TGS) for cholestatic between 2018-2023 at our center. Results TGS were reported as pathogenic, likely pathogenic or variant uncertain significance (VUS) based on recommendations American College Medical Genetics. 14 included had FIC-associated genes. Results: Genetic analysis identified 6 new variants. 1 patient mutation ATP8B1, 7 ABCB11, 2 ABCB4, TJP2, NR1H4 KIF12 gene. One PFIC-2 also VUS ABCC-2 (Dubin-Johnson syndrome). Patient showed homozygous heterozygous ACOX-2 (Bile acid synthesis defect type 6) CFTR (cystic fibrosis) gene, all VUS. Even though mutations, they correlated clinically. Patients usually presented within years age jaundice, sometimes itching occasionally clay stools. transplant (LT) age, few resolved jaundice others been advised LT. Conclusion: implicates that genomic responsible Indian may differ those other populations. More such data needed help better genotype-phenotype correlation.

Genetic basis of progressive familial intrahepatic cholestasis.

oo~~ssrvn familial intrahepatic cholestasis (PFIC), P originally known as Byler disease, was first described in an Amish kindred (1,2). It is an inherited disorder of childhood in which cholestasis of hepatocellular origin often presents in the neonatal period or the first year of life and leads to death from liver failure at ages ranging from infancy to adolescence. Cholangiograms show normal ...

Progressive familial intrahepatic cholestasis

Progressive familial intrahepatic cholestasis (PFIC) refers to a heterogeneous group of autosomal-recessive disorders of childhood that disrupt bile formation and present with cholestasis of hepatocellular origin. The exact prevalence remains unknown, but the estimated incidence varies between 1/50,000 and 1/100,000 births. Three types of PFIC have been identified and associated with mutations ...

Progressive Familial Intrahepatic Cholestasis - A Case Report

Introduction Progressive familial intrahepatic cholestasis (PFIC) represents a group of disorders which usually begin in the first months of life and progress to cirrhosis before the end of second decade. The disease occurs due to a defect in bile acid transport leading to cholestasis and resultant hepatocelluler injury1-3. Recent molecular and genetic studies have identified genes responsible ...

Locus heterogeneity in progressive familial intrahepatic cholestasis.

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....
