Gall stone disease is more common in patients with cirrhosis. This association has been well established in different studies. Among the various factors which predispose a patient with gall stone disease to have associated liver cirrhosis, genetics also plays an important role.
This study aims to do a genetic panel-based analysis of genes which are involved in cholestasis to find any association between liver cirrhosis and gall stone disease.
Patients with history of gall stone or history of cholecystectomy done for gall stone disease will be evaluated for the presence of liver cirrhosis by fibroscan and ultrasonography. Those patients with cirrhosis and without cirrhosis will undergo a panel based genetic test for the common cholestasis genes and multivariate analysis will be done for variants associated with lithogenesis and cirrhosis.
Study population:
Study period: 1 year. Intervention: Blood sample from included patients will be subject to panel based NGS.
Monitoring and assessment: History of all patients including family history will be taken. Screening for cirrhosis will be done by fibroscan or ultrasound scanning. Gall stone diagnosis is made by USG. History about patients' parents, siblings, spouse, children will be taken with respect to gall stone and cirrhosis. NGS of cholecystitis will be send for the subject and the results will be collected as the fastQ file for analysis.
Statistical Analysis: MVA will be done to identify gene variants independently associated with lithogenesis and cirrhosis, along with demographic and environmental risk factors for these conditions. * From this data, overlapping risk-variants in common associated genes will be identified. A risk estimate (OR with 95% CI) will be calculated for each of the above identified genetic risk variant for the phenotype of cirrhosis with GS.
Adverse effects:
There are no adverse outcomes with respect to this study. Stopping rule of study: There are no stopping rules for the study.

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
