Objectives: Idiopathic pancreatic hyperenzymemia is a new syndrome that is characterized by a chronic increase of serum pancreatic enzymes in the absence of pancreatic disease. The aim of this study was to assess whether mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene may have a role in the etiology of this hyperenzymemia. Methods: Seventy subjects with idiopathic pancreatic hyperenzymemia, 44 men and 26 women (mean age, 48 years; range, 8– 74 years), were studied. Thirteen of these 70 subjects had the familial form of the syndrome. The mutation analysis of the CFTR gene was carried out using diagnostic commercial kits for the simultaneous detection of 29 mutations and Tn polymorphism. Results: Among the 70 subjects studied, 7 (10.0%) had CFTR gene mutations. None of these 7 subjects had the familial form of pancreatic hyperenzymemia. These mutations were DF 508 in 1 subject, 2789 + 5G. A in another subject, and T5 allele in the remaining 5. All these mutations were heterozygous, with the exception of 1 T5 allele that was homozygous in 1 subject. Conclusions: The frequencies of the mutations of the CFTR gene found in these subjects are similar to the carrier frequencies in the general Italian population. This finding does not support a role for CFTR gene mutations in the etiology of idiopathic pancreatic hyperenzymemia.

Abstract

Objectives: Idiopathic pancreatic hyperenzymemia is a new syndrome that is characterized by a chronic increase of serum pancreatic enzymes in the absence of pancreatic disease. The aim of this study was to assess whether mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene may have a role in the etiology of this hyperenzymemia. Methods: Seventy subjects with idiopathic pancreatic hyperenzymemia, 44 men and 26 women (mean age, 48 years; range, 8– 74 years), were studied. Thirteen of these 70 subjects had the familial form of the syndrome. The mutation analysis of the CFTR gene was carried out using diagnostic commercial kits for the simultaneous detection of 29 mutations and Tn polymorphism. Results: Among the 70 subjects studied, 7 (10.0%) had CFTR gene mutations. None of these 7 subjects had the familial form of pancreatic hyperenzymemia. These mutations were DF 508 in 1 subject, 2789 + 5G. A in another subject, and T5 allele in the remaining 5. All these mutations were heterozygous, with the exception of 1 T5 allele that was homozygous in 1 subject. Conclusions: The frequencies of the mutations of the CFTR gene found in these subjects are similar to the carrier frequencies in the general Italian population. This finding does not support a role for CFTR gene mutations in the etiology of idiopathic pancreatic hyperenzymemia.
