WebCTRC mutations appear to boost the effects of the mutant forms of cationic trypsinogen ( Fig. 1; Szabo and Sahin-Toth 2012 ). Two alterations in the CTRC gene, R254W and K247_R254del, were significantly overrepresented in a study of cohorts of patients with idiopathic chronic pancreatitis and hereditary pancreatitis ( Rosendahl et al. 2008 ). WebCTRC G60G was in epistasis with CFTR and SPINK1 mutations as reflected by a higher frequency of the T allele among carriers (22.9%) but not with the limited number of PRSS1 or CTRC mutations (10.2%). We removed the samples with any known genetic risk factors and assessed the impact of c.180C>T within different etiologies.
