Summary
This review explores genetic factors in cholestasis, a condition of impaired bile flow. It covers primary genetic syndromes and genetic predispositions in acquired cholestatic diseases.
Area of Science:
- Hepatology and Gastroenterology
- Genetics and Molecular Biology
Background:
- Cholestasis is characterized by impaired bile flow, leading to the accumulation of biliary constituents in circulation.
- Causes include acute or chronic injury to liver cells (hepatocytes), bile duct cells (cholangiocytes), or the biliary tree.
- These injuries can stem from primary genetic defects or a combination of genetic predisposition and environmental factors like drug exposure.
Purpose of the Study:
- To provide an overview of fundamental primary genetic cholestatic syndromes.
- To update knowledge on the genetic predispositions underlying acquired cholestatic processes.
Main Methods:
- Literature review of primary genetic cholestatic syndromes.
- Analysis of genetic factors contributing to acquired cholestasis.
Main Results:
- Identified key primary genetic abnormalities causing cholestasis.
- Highlighted the role of genetic predisposition in acquired cholestatic conditions, particularly in response to environmental triggers.
Conclusions:
- Genetic factors play a crucial role in both primary and acquired forms of cholestasis.
- Understanding these genetic underpinnings is vital for diagnosing and managing cholestatic liver diseases.

01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
01:29Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:16Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters
The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
