The purpose of this study is to establish linkage in families with hereditary pancreatitis (HP) to the cationic trypsinogen gene or other, as yet unknown, HP gene(s).

Study summary:

Hereditary Pancreatitis (HP) is an inflammatory condition of the pancreas which is usually recurrent in nature and occurs in blood-related persons over two or more generations. It is an autosomal dominant trait with complete penetrance by variable expression. Symptoms are usually present during childhood and it is the second most common cause of chronic or recurrent pancreatitis in children. HP is a primary disorder and can therefore be differentiated from other inherited disorders that cause secondary pancreatitis. The purpose of this study is to establish linkage in families with HP between the phenotype and a chromosomal locus (loci) which contains the responsible gene. Affected families are recruited to donate a blood sample through referral from their primary physician or self-referral. The potential significance lies in the identification of the genetic defect causing HP and understanding the pathophysiologic mechanism of the disease. Typically families with HP have a high incidence of adenocarcinoma of the pancreas and identification of the cause of this disease may provide critical insights into the cause of pancreatic cancer. Blood samples are collected from patients and family members. DNA is extracted from the blood and used for genotypic analysis and linkage analysis. Patients do not necessarily receive the results of the genetic testing and the results do not influence the type or duration of treatment.


1. Diagnosis of pancreatitis at age < 60 OR 2. Diagnosis of pancreatitis at any age and at least one other 1st or 2nd degree relative with a diagnosis of pancreatitis or pancreatic cancer OR 3. Diagnosis of pancreatic cancer and a 1st or 2nd degree relative with pancreatic cancer or pancreatitis OR 4. Diagnosis of pancreatic insufficiency or maldigestion that improves with pancreatic enzyme replacement OR 5. Close family members (parents, grandparents, siblings cousins - anyone related by blood) of subjects who meet criteria 1, 2, or 3 AND 6. Age 3 months up to 100 years
