RESUMO

This study reported a family of mitochondrial diabetes mellitus complicated with chronic hereditary pancreatitis. A 18-year-old woman presented with self-reported hyperglycemia and chronic epigastric pain was admitted to our hospital. Clinical data and family history were collected. Mitochondrial gene sequencing and whole exon gene sequencing showed that the proband carried mutation of mt.3243A>G and heterozygous mutation of SPINK1 c. 194+ 2T>C, which was considered as mitochondrial diabetes mellitus with chronic pancreatitis.

RESUMO

The etiopathogenesis of tropical chronic pancreatitis (TCP) remains unclear. Malnutrition, dietary toxins like cyanogens in cassava and micronutrient deficiency are proposed factors. The description and characterization of genetic factors in TCP has added a new dimension to the understanding of pathogenesis of the disease. However, there is sparse data on the association of TCP with cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations. We report 8 patients of TCP with CFTR gene mutations, including one with a novel mutation, and describe the clinical profile of these patients. Further prospective genetic studies on the association of CFTR gene mutations are essential in order to unravel the genetic basis of TCP.

RESUMO

BACKGROUND/AIMS: It has been found that mutations of cationic trypsinogen gene (PRSS1) and serine protease inhibitor, Kazal type 1 gene (SPINK1) increase the susceptibility of chronic pancreatitis (CP). Specifically, mutations in the PRSS1 gene are related to the occurrences of hereditary and idiopathic pancreatitis while SPINK1 mutations are known to act as a disease modifier and are associated with idiopathic CP. However, the association of SPINK1 mutations with alcoholic CP is still controversial. We investigated the prevalence of PRSS1 and SPINK1 mutations in idiopathic and alcoholic CP in Korea. METHODS: Seventy-one Korean patients with CP (alcoholic: 47, idiopathic: 22 and familial: 2) and 19 controls were included in this studies. Genomic DNA was extracted from peripheral blood of the patients. Mutations of SPINK1 (exon 3: N34S) and PRSS1 (exon 2: N29I, exon 3: R122H) genes were detected by PCR-RFLP methods. For the detection of SPINK1 mutation, restriction endonuclease PstI and BsrDI were used, while Sau3A and AflIII were used for the defection of PRSS1 mutation. RESUTLS: Only one patient (2.1%) with alcoholic CP was a heterozygote for SPINK1 (N34S) mutation. Mutation in the PRSS1 (N29I, R122H) gene was not found in any group of CP patients. Additionally, we could not find any mutations of SPINK1 or PRSS1 in the control group. CONCLUSIONS: SPINK1 and PRSS1 mutations are not related to the development of CP in Korea.
