In a study of 901 individuals with idiopathic or hereditary chronic pancreatitis (167800) and 2,804 control subjects of German origin, Rosendahl et al. (2008) found that a 760C-T transition in exon 7 of the CTRC gene, resulting in an arg254-to-trp amino acid substitution (R254W), was significantly overrepresented among affected individuals (19/901; 2.1%, P = 0.0004) compared to controls (18/2804; 0.6%). Investigation of an independent cohort of 348 German individuals with alcohol-related chronic pancreatitis and 432 controls confirmed this finding (2.3% in affected individuals vs 0.5% in controls). Enrichment of the R254W variant in 71 Indian subjects with tropical pancreatitis (608189) did not reach statistical significance.

Masson et al. (2008) sequenced the CTRC gene in 287 white French patients with idiopathic chronic pancreatitis and identified the R254W mutation in 5 sporadic patients and 1 of 350 controls.
