We have studied a family in which three people, two child and an adult had hereditary pancreatitis. Hereditary pancreatitis is not a common disease. Abdominal pain is usually the first clinical sign in children. The knowledge of the existence of such a disease and familiarity with the family history of the child allow the pediatrician to make the diagnosis as soon as the first crisis appears. Surgery is thus avoided. Our studies show definitively that this disease is hereditary and is autosomal dominant with a strong decrease of the penetrance.

Information from 72 patients from 7 families in England and Wales confirms that hereditary pancreatitis is inherited as an autosomal dominant conditions with limited penetrance. The degree of penetrance is approximately 80%. These patients have had recurrent attacks of abdominal pain starting from childhood or young adult life. The mean age of onset in the 7 families studied was 13.6 years. There were two peaks, with maximum numbers at 5 years and 17 years. The second peak was thought to represent genetically susceptible individuals having pain brought on by alcohol rather than representing evidence of genetic heterogeneity. Five of the 7 families had members with both childhood and adult ages of onset. Only 4 patients out of 72 had life-threatening disease and in the majority of cases the attacks of pain were of nuisance value only. Hereditary pancreatitis was implicated in only 1 patient's death and this was not definite. Patients appear to get better after a period of symptoms usually as they approach middle age, or after a severe attack. In older patients alcohol, emotional upsets, and fatty food appear to precipitate attacks. Pancreatic insufficiency (5.5%), diabetes mellitus (12.5%), pseudocysts (5.5%), and haemorrhagic pleural effusion are uncommon complications. Portal vein thrombosis occurred definitely in 2 patients and was suspected in 3 others. Carcinoma of the pancreas was not found in any of 72 patients studied in detail; however, 2 members from a family not visited personally had chronic pancreatitis and malabsorption going on to carcinoma. They may have suffered from a different disease. Genetic linkage information was too slight for many definite conclusions. However, there was no suggestion of linkage with any of the markers tested.

Hereditary pancreatitis was diagnosed in dystrophic boy at the age of 2 1/2 years after recurring episodes of severe abdominal pain. Extensive left-sided pleural effusions caused surgical exploration. Pancreatography showed typical dilation of the pancreatic ductal system. After hemipancreatectomy by the boy recovered very fast. Characteristic features in diagnosing of hereditary pancreatitis are the onset of recurring attacks of abdominal pain in early childhood and anatomical defects in the pancreatic ductal system. The disease shows variability between family members.

Hereditary pancreatitis is an autosomal dominant disease with no other known cause. It usually begins in childhood and is characterized by recurrent attacks of abdominal pain of variable intensity and duration, followed by symptom-free periods. The diagnosis is usually made in early adult life, when pancreatic insufficiency and calcifications appear. Complications are less frequent than in nonhereditary chronic pancreatitis. There are also differences between the two forms of chronic pancreatitis in sex incidence, etiologic factors and life expectancy. In a Canadian kindred three generations are affected with hereditary pancreatitis; there are four definite and four suspected cases. More than 40 affected kindreds, including 195 proven cases and 190 suspected cases, have now been reported in the literature. Thus, hereditary pancreatitis should be considered in the differential diagnosis of chronic relapsing pancreatitis of unknown cause as well as recurrent abdominal pain in childhood.

Hereditary pancreatitis (HP) is a rare cause of chronic pancreatitis. Recurrent abdominal pain is the most common clinical manifestation, with onset in childhood or adolescence. PURPOSE--Report of a case of HP with atypical presentation and a review of the literature. METHODS--A non-alcoholic patient, without history of abdominal pain, with steatorrhea and malnutrition was investigated. The diagnostic evaluation revealed severe chronic pancreatitis. Two close relatives with early onset calcifying pancreatitis were detected. Epidemiologic and clinical features of HP were reviewed. CONCLUSION--Although uncommon, HP should be regarded in the differential diagnosis of chronic pancreatitis. Familial screening of suspected cases should be routinely performed.

Hereditary pancreatitis (HP) is an uncommon disorder previously described in only two Danish families. A third family with HP is presented. The diagnosis of HP should be considered in a child with unexplained relapsing abdominal pain, and in particular with a positive family history.

Hereditary pancreatitis (HP) is an autosomal dominant disorder with incomplete penetrance characterized by recurring episodes of severe abdominal pain often presenting in childhood. Although this disorder has only been recently described, about 100 families have been documented worldwide. The pathophysiology of this disorder is unknown. Here, a large French family of 147 individuals (47 of whom were affected) from a four-generation kindred with HP has been examined and a genome segregation analysis of highly informative microsatellite markers has been performed. Linkage has been found between HP and six chromosome 7q markers. Maximal two point lod scores between HP and D7S 640, D7S 495, D7S 684, D7S 661, D7S 676 and D7S 688 were 4.00 (theta = 0.143), 5.85 (theta = 0.143), 4.91 (theta = 0.156), 8.58 (theta = 0.077), 8.28 (theta = 0.060), 4.40 (theta = 0.169), respectively. Multipoint linkage data combined with recombinant haplotype analysis indicated that the most likely order is: D7S 640-D7S 495-D7S 684-D7S 661-D7S 676-D7S 688, with the HP gene situated in the underlined region. As in all families reported in the literature, the clinical presentation of the disease is identical to the presentation of sporadic cases, one could expect that the knowledge of the HP gene could be a clue to pancreatitis in general. Based on its map position, this is the first step towards the positional cloning of the Hereditary Pancreatitis Gene (HPG).

Hereditary pancreatitis is an autosomal dominant disorder with incomplete penetrance. It is characterised by recurring episodes of severe abdominal pain and often presents in childhood. Recently, a mutation in the cationic trypsinogen gene was identified in this disease. Previously, only one mutation at residue 117 of the trypsinogen gene has been found in the five separate hereditary pancreatitis families, four from the USA and one from Italy. Alteration of the Arg117 site is believed to disrupt a fail-safe mechanism for the inactivation of trypsin, leading to autodigestion of the pancreas under certain conditions. Molecular analysis of the trypsinogen gene was carried out on a hereditary pancreatitis family from the UK. The same G to A mutation at residue 117 was identified in this family, suggesting that this is a common mutation in hereditary pancreatitis.

Hereditary pancreatitis (HP) is an autosomal dominant disorder characterized by recurrent acute attacks of severe abdominal pain with an onset in early childhood. Many HP patients progress to complicated chronic pancreatitis and/or pancreatic cancer. Initially, a single mutation R117H in the cationic trypsinogen gene was detected in all affected members of five unrelated HP families. Further studies identified a second mutation (N21L) in two HP families without the R117H mutation. Before the association between cationic trypsinogen and HP was found, we detected a cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation (L327R) in all affected individuals of a family with HP. We therefore performed a mutational analysis for R117H and N21L in cationic trypsinogen in this and three additional unrelated families with HP. The R117H mutation was detected in all 9 affected members of three HP families and in 3 asymptomatic but at-risk relatives. However, neither the R117H nor the N21L mutation in the cationic trypsinogen were found in the HP family with the L327R alteration in CFTR. The L327R allele segregates with the disease within this HP family and was not detected on 360 unrelated Caucasian non-CF chromosomes. Although close to 800 different mutations have been detected in the CF gene of cystic fibrosis patients, L327R is a new alteration, not yet reported in connection with CF. The results of this study indicate that the CFTR gene may play a role in the etiology of minority of cases with HP and suggest that hereditary pancreatitis is genetically heterogeneous disease.

Hereditary pancreatitis is an autosomal dominant form of chronic pancreatitis. It presents with recurrent attacks of acute pancreatitis, usually starting in early childhood. The attacks may vary from mild abdominal pain to pancreatic necrosis, splenic vein thrombosis, pseudocysts and death. Ultimately chronic pancreatitis ensues with unrelenting pain, calcifications, endocrine and exocrine dysfunction. The penetrance is estimated at 80%. With the use of genetic linkage analysis the gene for hereditary pancreatitis was placed on the long arm of chromosome 7 (7q35). Mutational analysis identified cationic trypsinogen as the disease gene. Cationic trypsinogen mutations are thought to result in resistance of this molecule to autolysis.
